CVE ID Vulnerability Description Maximum Severity Rating Vulnerability Impact
CVE-2018-8175
MITRE
NVD
CVE Title: WEBDAV Denial of Service Vulnerability
Description:

An denial of service vulnerability exists when Windows NT WEBDAV Minirdr attempts to query a WEBDAV directory. An attacker who successfully exploited the vulnerability could cause a denial of service.

To exploit the vulnerability, an attacker could host a specially crafted website and then convince a user to browse to it, which would cause the victim's system to stop responding. However, an attacker could not force a user to view the attacker-controlled content. Instead, an attacker would have to convince a user to take action. For example, an attacker could trick a user into clicking a link that takes the user to the attacker's WEBDAV directory.

The security update addresses the vulnerability by correcting how Windows NT WEBDAV Minirdr attempts to query a WEBDAV directory.

CVE ID Vulnerability Description Maximum Severity Rating Vulnerability Impact
CVE-2018-8201
MITRE
NVD
CVE Title: Device Guard Code Integrity Policy Security Feature Bypass Vulnerability
Description:

A security feature bypass vulnerability exists in Device Guard that could allow an attacker to inject malicious code into a Windows PowerShell session. An attacker who successfully exploited this vulnerability could inject code into a trusted PowerShell process to bypass the Device Guard Code Integrity policy on the local machine.

To exploit the vulnerability, an attacker would first have to access the local machine, and then inject malicious code into a script that is trusted by the Code Integrity policy. The injected code would then run with the same trust level as the script and bypass the Code Integrity policy.

The update addresses the vulnerability by correcting how PowerShell exposes functions and processes user supplied code.

CVE ID Vulnerability Description Maximum Severity Rating Vulnerability Impact
CVE-2018-8211
MITRE
NVD
CVE Title: Device Guard Code Integrity Policy Security Feature Bypass Vulnerability
Description:

A security feature bypass vulnerability exists in Device Guard that could allow an attacker to inject malicious code into a Windows PowerShell session. An attacker who successfully exploited this vulnerability could inject code into a trusted PowerShell process to bypass the Device Guard Code Integrity policy on the local machine.

To exploit the vulnerability, an attacker would first have to access the local machine, and then inject malicious code into a script that is trusted by the Code Integrity policy. The injected code would then run with the same trust level as the script and bypass the Code Integrity policy.

The update addresses the vulnerability by correcting how PowerShell exposes functions and processes user supplied code.

CVE Title: Windows Desktop Bridge Elevation of Privilege Vulnerability
Description:

An elevation of privilege vulnerability exists in Windows when Desktop Bridge does not properly manage the virtual registry. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system.

The update addresses this vulnerability by correcting how the Windows Desktop Bridge manages the virtual registry.

CVE Title: Device Guard Code Integrity Policy Security Feature Bypass Vulnerability
Description:

A security feature bypass vulnerability exists in Device Guard that could allow an attacker to inject malicious code into a Windows PowerShell session. An attacker who successfully exploited this vulnerability could inject code into a trusted PowerShell process to bypass the Device Guard Code Integrity policy on the local machine.

To exploit the vulnerability, an attacker would first have to access the local machine, and then inject malicious code into a script that is trusted by the Code Integrity policy. The injected code would then run with the same trust level as the script and bypass the Code Integrity policy.

The update addresses the vulnerability by correcting how PowerShell exposes functions and processes user supplied code.

An attacker who successfully exploited this vulnerability could gain elevated privileges on a target guest operating system. The host operating system is not vulnerable to this attack.

This vulnerability by itself does not allow arbitrary code to be run. However, the vulnerability could be used in conjunction with one or more vulnerabilities (e.g. a remote code execution vulnerability and another elevation of privilege) that could take advantage of the elevated privileges when running.

The update addresses the vulnerability by correcting how privileges are enforced by Windows Hyper-V instruction emulation.

CVE ID Vulnerability Description Maximum Severity Rating Vulnerability Impact
CVE-2018-8221
MITRE
NVD
CVE Title: Device Guard Code Integrity Policy Security Feature Bypass Vulnerability
Description:

A security feature bypass vulnerability exists in Device Guard that could allow an attacker to inject malicious code into a Windows PowerShell session. An attacker who successfully exploited this vulnerability could inject code into a trusted PowerShell process to bypass the Device Guard Code Integrity policy on the local machine.

To exploit the vulnerability, an attacker would first have to access the local machine, and then inject malicious code into a script that is trusted by the Code Integrity policy. The injected code would then run with the same trust level as the script and bypass the Code Integrity policy.

The update addresses the vulnerability by correcting how PowerShell exposes functions and processes user supplied code.

CVE Title: HTTP.sys Denial of Service Vulnerability
Description:

A denial of service vulnerability exists in the HTTP 2.0 protocol stack (HTTP.sys) when HTTP.sys improperly parses specially crafted HTTP 2.0 requests. An attacker who successfully exploited the vulnerability could create a denial of service condition, causing the target system to become unresponsive.

To exploit this vulnerability, an attacker could send a specially crafted HTTP packet to a target system, causing the affected system to become nonresponsive.

The update addresses the vulnerability by modifying how the Windows HTTP protocol stack handles HTTP 2.0 requests. Note that the denial of service vulnerability would not allow an attacker to execute code or to elevate user rights.

CVE-2018-8227
MITRE

CVE Title: Chakra Scripting Engine Memory Corruption Vulnerability
Description:

A remote code execution vulnerability exists in the way that the Chakra scripting engine handles objects in memory in Microsoft Edge. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Microsoft Edge and then convince a user to view the website. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit the vulnerability.

The security update addresses the vulnerability by modifying how the Chakra scripting engine handles objects in memory.

CVE Title: Microsoft Outlook Elevation of Privilege Vulnerability
Description:

An elevation of privilege vulnerability exists when Microsoft Outlook does not validate attachment headers properly. An attacker who successfully exploited the vulnerability could send an email with hidden attachments that would be opened or executed once a victim clicks a link within the email. Note that this does not bypass attachment filters, so blocked attachments will still be excluded.

To exploit the vulnerability, the attacker could send a specially crafted email to a victim. The victim would then be required to click on a link within the email to open or execute a malicious attachment.

This update addresses the vulnerability by changing the way that Outlook parses attachment headers.

CVE-2018-8248
MITRE
NVD
CVE Title: Microsoft Excel Remote Code Execution Vulnerability
Description:

A remote code execution vulnerability exists in Microsoft Excel software when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Excel. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) containing a specially crafted file designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file.

The security update addresses the vulnerability by correcting how Microsoft Excel handles objects in memory.

CVE Title: June 2018 Adobe Flash Security Update
Description:

This security update addresses the following vulnerabilities, which are described in Adobe Security Bulletin APSB18-19: CVE-2018-4945, CVE-2018-5000, CVE-2018-5001, CVE-2018-5002.


FAQ:

How could an attacker exploit these vulnerabilities? In a web-based attack scenario where the user is using Internet Explorer for the desktop, an attacker could host a specially crafted website that is designed to exploit any of these vulnerabilities through Internet Explorer and then convince a user to view the website. An attacker could also embed an ActiveX control marked "safe for initialization" in an application or Microsoft Office document that hosts the IE rendering engine. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit any of these vulnerabilities. In all cases, however, an attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by clicking a link in an email message or in an Instant Messenger message that takes users to the attacker's website, or by opening an attachment sent through email.

In a web-based attack scenario where the user is using Internet Explorer in the Windows 8-style UI, an attacker would first need to compromise a website already listed in the Compatibility View (CV) list. An attacker could then host a website that contains specially crafted Flash content designed to exploit any of these vulnerabilities through Internet Explorer and then convince a user to view the website. An attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by clicking a link in an email message or in an Instant Messenger message that takes users to the attacker's website, or by opening an attachment sent through email. For more information about Internet Explorer and the CV List, please see the MSDN Article, Developer Guidance for websites with content for Adobe Flash Player in Windows 8.

Workarounds:

Workaround refers to a setting or configuration change that would help block known attack vectors before you apply the update.

Prevent Adobe Flash Player from running You can disable attempts to instantiate Adobe Flash Player in Internet Explorer and other applications that honor the kill bit feature, such as Office 2007 and Office 2010, by setting the kill bit for the control in the registry.

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk. To set the kill bit for the control in the registry, perform the following steps:

  1. Paste the following into a text file and save it with the .reg file extension.

     Windows Registry Editor Version 5.00
     [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{D27CDB6E-AE6D-11CF-96B8-444553540000}]
     "Compatibility Flags"=dword:00000400
    
     [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\ActiveX Compatibility\{D27CDB6E-AE6D-11CF-96B8-444553540000}]
     "Compatibility Flags"=dword:00000400
    
  2. Double-click the .reg file to apply it to an individual system.

    You can also apply this workaround across domains by using Group Policy. For more information about Group Policy, see the TechNet article, Group Policy collection.

Note You must restart Internet Explorer for your changes to take effect. Impact of workaround. There is no impact as long as the object is not intended to be used in Internet Explorer. How to undo the workaround. Delete the registry keys that were added in implementing this workaround. Prevent Adobe Flash Player from running in Internet Explorer through Group Policy Note The Group Policy MMC snap-in can be used to set policy for a machine, for an organizational unit, or for an entire domain. For more information about Group Policy, visit the following Microsoft Web sites:

Group Policy Overview What is Group Policy Object Editor? Core Group Policy tools and settings

To disable Adobe Flash Player in Internet Explorer through Group Policy, perform the following steps: Note This workaround does not prevent Flash from being invoked from other applications, such as Microsoft Office 2007 or Microsoft Office 2010.

  1. Open the Group Policy Management Console and configure the console to work with the appropriate Group Policy object, such as local machine, OU, or domain GPO.
  2. Navigate to the following node: Administrative Templates -> Windows Components -> Internet Explorer -> Security Features -> Add-on Management
  3. Double-click Turn off Adobe Flash in Internet Explorer and prevent applications from using Internet Explorer technology to instantiate Flash objects.
  4. Change the setting to Enabled.
  5. Click Apply and then click OK to return to the Group Policy Management Console.
  6. Refresh Group Policy on all systems or wait for the next scheduled Group Policy refresh interval for the settings to take effect. Prevent Adobe Flash Player from running in Office 2010 on affected systems Note This workaround does not prevent Adobe Flash Player from running in Internet Explorer. Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk. For detailed steps that you can use to prevent a control from running in Internet Explorer, see Microsoft Knowledge Base Article 240797. Follow the steps in the article to create a Compatibility Flags value in the registry to prevent a COM object from being instantiated in Internet Explorer.

To disable Adobe Flash Player in Office 2010 only, set the kill bit for the ActiveX control for Adobe Flash Player in the registry using the following steps:

  1. Create a text file named Disable_Flash.reg with the following contents:
		[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Common\COM\Compatibility\{D27CDB6E-AE6D-11CF-96B8-444553540000}]
	"Compatibility Flags"=dword:00000400
  1. Double-click the .reg file to apply it to an individual system.
  2. Note You must restart Internet Explorer for your changes to take effect. You can also apply this workaround across domains by using Group Policy. For more information about Group Policy, see the TechNet article, Group Policy collection. Prevent ActiveX controls from running in Office 2007 and Office 2010

To disable all ActiveX controls in Microsoft Office 2007 and Microsoft Office 2010, including Adobe Flash Player in Internet Explorer, perform the following steps:

  1. Click File, click Options, click Trust Center, and then click Trust Center Settings.
  2. Click ActiveX Settings in the left-hand pane, and then select Disable all controls without notifications.
  3. Click OK to save your settings. Impact of workaround. Office documents that use embedded ActiveX controls may not display as intended. How to undo the workaround.

To re-enable ActiveX controls in Microsoft Office 2007 and Microsoft Office 2010, perform the following steps:

  1. Click File, click Options, click Trust Center, and then click Trust Center Settings.
  2. Click ActiveX Settings in the left-hand pane, and then deselect Disable all controls without notifications.
  3. Click OK to save your settings. Set Internet and Local intranet security zone settings to "High" to block ActiveX Controls and Active Scripting in these zones You can help protect against exploitation of these vulnerabilities by changing your settings for the Internet security zone to block ActiveX controls and Active Scripting. You can do this by setting your browser security to High.

To raise the browsing security level in Internet Explorer, perform the following steps:

  1. On the Internet Explorer Tools menu, click** Internet Option**s.
  2. In the Internet Options dialog box, click the Security tab, and then click Internet.
  3. Under Security level for this zone, move the slider to High. This sets the security level for all websites you visit to High.
  4. Click Local intranet.
  5. Under Security level for this zone, move the slider to High. This sets the security level for all websites you visit to High.
  6. Click OK to accept the changes and return to Internet Explorer. Note If no slider is visible, click Default Level, and then move the slider to High. Note Setting the level to High may cause some websites to work incorrectly. If you have difficulty using a website after you change this setting, and you are sure the site is safe to use, you can add that site to your list of trusted sites. This will allow the site to work correctly even with the security setting set to High. Impact of workaround. There are side effects to blocking ActiveX Controls and Active Scripting. Many websites on the Internet or an intranet use ActiveX or Active Scripting to provide additional functionality. For example, an online e-commerce site or banking site may use ActiveX Controls to provide menus, ordering forms, or even account statements. Blocking ActiveX Controls or Active Scripting is a global setting that affects all Internet and intranet sites. If you do not want to block ActiveX Controls or Active Scripting for such sites, use the steps outlined in "Add sites that you trust to the Internet Explorer Trusted sites zone". Configure Internet Explorer to prompt before running Active Scripting or to disable Active Scripting in the Internet and Local intranet security zone

You can help protect against exploitation of these vulnerabilities by changing your settings to prompt before running Active Scripting or to disable Active Scripting in the Internet and Local intranet security zone. To do this, perform the following steps:

  1. In Internet Explorer, click Internet Options on the Tools menu.
  2. Click the Security tab.
  3. Click Internet, and then click Custom Level.
  4. Under Settings, in the Scripting section, under Active Scripting, click Prompt or Disable, and then click OK.
  5. Click Local intranet, and then click Custom Level.
  6. Under Settings, in the Scripting section, under Active Scripting, click Prompt or Disable, and then click OK.
  7. Click OK to return to Internet Explorer, and then click OK again. Note Disabling Active Scripting in the Internet and Local intranet security zones may cause some websites to work incorrectly. If you have difficulty using a website after you change this setting, and you are sure the site is safe to use, you can add that site to your list of trusted sites. This will allow the site to work correctly. Impact of workaround. There are side effects to prompting before running Active Scripting. Many websites that are on the Internet or on an intranet use Active Scripting to provide additional functionality. For example, an online e-commerce site or banking site may use Active Scripting to provide menus, ordering forms, or even account statements. Prompting before running Active Scripting is a global setting that affects all Internet and intranet sites. You will be prompted frequently when you enable this workaround. For each prompt, if you feel you trust the site that you are visiting, click Yes to run Active Scripting. If you do not want to be prompted for all these sites, use the steps outlined in "Add sites that you trust to the Internet Explorer Trusted sites zone". Add sites that you trust to the Internet Explorer Trusted sites zone After you set Internet Explorer to require a prompt before it runs ActiveX controls and Active Scripting in the Internet zone and in the Local intranet zone, you can add sites that you trust to the Internet Explorer Trusted sites zone. This will allow you to continue to use trusted websites exactly as you do today, while helping to protect you from this attack on untrusted sites. We recommend that you add only sites that you trust to the Trusted sites zone.

To do this, perform the following steps:

  1. In Internet Explorer, click Tools, click Internet Options, and then click the Security tab.
  2. In the Select a web content zone to specify its current security settings box, click Trusted Sites, and then click Sites.
  3. If you want to add sites that do not require an encrypted channel, click to clear the Require server verification (https:) for all sites in this zone check box.
  4. In the Add this website to the zone box, type the URL of a site that you trust, and then click Add.
  5. Repeat these steps for each site that you want to add to the zone.
  6. Click OK two times to accept the changes and return to Internet Explorer. Note Add any sites that you trust not to take malicious action on your system. Two sites in particular that you may want to add are *.windowsupdate.microsoft.com and *.update.microsoft.com. These are the sites that will host the update, and they require an ActiveX control to install the update.

CVE-2018-0978
MITRE
NVD
CVE Title: Internet Explorer Memory Corruption Vulnerability
Description:

A remote code execution vulnerability exists when Internet Explorer improperly accesses objects in memory. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, the attacker could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

An attacker could host a specially crafted website designed to exploit the vulnerability through Internet Explorer and then convince a user to view the website. The attacker could also take advantage of compromised websites, or websites that accept or host user-provided content or advertisements, by adding specially crafted content that could exploit the vulnerability. However, in all cases an attacker would have no way to force a user to view the attacker-controlled content. Instead, an attacker would have to convince a user to take action, typically by an enticement in an email or instant message, or by getting the user to open an attachment sent through email.

The security update addresses the vulnerability by modifying how Internet Explorer handles objects in memory.

CVE Title: Windows Code Integrity Module Denial of Service Vulnerability
Description:

A denial of service vulnerability exists in the way that the Windows Code Integrity Module performs hashing.

An attacker who successfully exploited the vulnerability could cause a system to stop responding. Note that the denial of service condition would not allow an attacker to execute code or to elevate user privileges. However, the denial of service condition could prevent authorized users from using system resources.

An attacker could host a specially crafted file in a website or SMB share. The attacker could also take advantage of compromised websites, or websites that accept or host user-provided content or advertisements, by adding specially crafted content that could exploit the vulnerability. However, in all cases an attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically via an enticement in email or instant message, or by getting them to open an email attachment.

The security update addresses the vulnerability by modifying how the Code Integrity Module performs hashing.

CVE Title: Microsoft Edge Memory Corruption Vulnerability
Description:

A remote code execution vulnerability exists when Microsoft Edge improperly accesses objects in memory. The vulnerability could corrupt memory in such a way that enables an attacker to execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

An attacker could host a specially crafted website that is designed to exploit the vulnerability through Microsoft Edge, and then convince a user to view the website. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements by adding specially crafted content that could exploit the vulnerability. In all cases, however, an attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by way of enticement in an email or Instant Messenger message, or by getting them to open an attachment sent through email.

The security update addresses the vulnerability by modifying how Microsoft Edge handles objects in memory.

CVE-2018-8113
MITRE
NVD
CVE Title: Internet Explorer Security Feature Bypass Vulnerability
Description:

A security feature bypass vulnerability exists in Internet Explorer that allows for bypassing Mark of the Web Tagging (MOTW). Failing to set the MOTW means that a large number of Microsoft security technologies are bypassed.

In a web-based attack scenario, an attacker could host a malicious website that is designed to exploit the security feature bypass. Alternatively, in an email or instant message attack scenario, the attacker could send the targeted user a specially crafted .url file that is designed to exploit the bypass. Additionally, compromised websites or websites that accept or host user-provided content could contain specially crafted content to exploit the security feature bypass. However, in all cases an attacker would have no way to force a user to view attacker-controlled content. Instead, an attacker would have to convince a user to take action. For example, an attacker could entice a user to either click a link that directs the user to the attacker's site or send a malicious attachment.

The security update addresses the security feature bypass by correcting how Internet Explorer handles MOTW tagging.

CVE Title: Microsoft Edge Information Disclosure Vulnerability
Description:

An information disclosure vulnerability exists when Microsoft Edge improperly handles objects in memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user’s system.

To exploit the vulnerability, in a web-based attack scenario, an attacker could host a website in an attempt to exploit the vulnerability. In addition, compromised websites and websites that accept or host user-provided content could contain specially crafted content that could exploit the vulnerability. However, in all cases an attacker would have no way to force a user to view the attacker-controlled content. Instead, an attacker would have to convince a user to take action. For example, an attacker could trick a user into clicking a link that takes the user to the attacker's site.

The update addresses the vulnerability by modifying how Microsoft Edge handles objects in memory.


FAQ:

What type of information could be disclosed by this vulnerability?

The type of information that could be disclosed if an attacker successfully exploited this vulnerability is uninitialized memory.

CVE Title: Microsoft Edge Security Feature Bypass Vulnerability
Description:

A security feature bypass vulnerability exists when Microsoft Edge improperly handles requests of different origins. The vulnerability allows Microsoft Edge to bypass Same-Origin Policy (SOP) restrictions, and to allow requests that should otherwise be ignored. An attacker who successfully exploited the vulnerability could force the browser to send data that would otherwise be restricted.

In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Microsoft Edge and then convince a user to view the website. The attacker could also take advantage of compromised websites, and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit the vulnerability.

The security update addresses the vulnerability by modifying how affected Microsoft Edge handles different-origin requests.

CVE Title: Microsoft Edge Memory Corruption Vulnerability
Description:

A remote code execution vulnerability exists when Microsoft Edge improperly accesses objects in memory. The vulnerability could corrupt memory in such a way that enables an attacker to execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

An attacker could host a specially crafted website that is designed to exploit the vulnerability through Microsoft Edge, and then convince a user to view the website. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements by adding specially crafted content that could exploit the vulnerability. In all cases, however, an attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by way of enticement in an email or Instant Messenger message, or by getting them to open an attachment sent through email.

The security update addresses the vulnerability by modifying how Microsoft Edge handles objects in memory.

CVE Title: Internet Explorer Memory Corruption Vulnerability
Description:

A remote code execution vulnerability exists when Internet Explorer improperly accesses objects in memory. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, the attacker could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

An attacker could host a specially crafted website designed to exploit the vulnerability through Internet Explorer and then convince a user to view the website. The attacker could also take advantag
