CVE ID Vulnerability Description Maximum Severity Rating Vulnerability Impact
CVE-2018-0816
MITRE
NVD
CVE Title: Windows GDI Elevation of Privilege Vulnerability
Description:

An elevation of privilege vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles objects in memory. 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 the vulnerability by correcting how GDI handles objects in memory and by preventing instances of unintended user-mode privilege elevation.

CVE Title: Windows GDI Elevation of Privilege Vulnerability
Description:

An elevation of privilege vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles objects in memory. 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 the vulnerability by correcting how GDI handles objects in memory and by preventing instances of unintended user-mode privilege elevation.

CVE Title: Windows Installer Elevation of Privilege Vulnerability
Description:

An elevation of privilege vulnerability exists in the Windows Installer when the Windows Installer fails to properly sanitize input leading to an insecure library loading behavior.

A locally authenticated attacker could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

The security update addresses the vulnerability by correcting the input sanitization error to preclude unintended elevation.

CVE-2018-0886 - CredSSP Remote Code Execution Vulnerability

(top)
CVE ID Vulnerability Description Maximum Severity Rating Vulnerability Impact
CVE-2018-0886
MITRE
NVD
CVE Title: CredSSP Remote Code Execution Vulnerability
Description:

A remote code execution vulnerability exists in the Credential Security Support Provider protocol (CredSSP). An attacker who successfully exploited this vulnerability could relay user credentials and use them to execute code on the target system.

CredSSP is an authentication provider which processes authentication requests for other applications; any application which depends on CredSSP for authentication may be vulnerable to this type of attack.

As an example of how an attacker would exploit this vulnerability against Remote Desktop Protocol, the attacker would need to run a specially crafted application and perform a man-in-the-middle attack against a Remote Desktop Protocol session. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

The security update addresses the vulnerability by correcting how Credential Security Support Provider protocol (CredSSP) validates requests during the authentication process.

To be fully protected against this vulnerability users must enable Group Policy settings on their systems and update their Remote Desktop clients. The Group Policy settings are disabled by default to prevent connectivity problems and users must follow the instructions documented HERE to be fully protected.

CVE-2018-0889
MITRE

CVE Title: Scripting Engine Memory Corruption Vulnerability
Description:

A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. 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 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 the vulnerability.

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

CVE-2018-0891 - Scripting Engine Information Disclosure Vulnerability

CVE ID Vulnerability Description Maximum Severity Rating Vulnerability Impact
CVE-2018-0891
MITRE
NVD
CVE Title: Scripting Engine Information Disclosure Vulnerability
Description:

An information disclosure vulnerability exists when the scripting engine does not properly handle objects in memory in Microsoft browsers. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user’s system.

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 security update addresses the vulnerability by changing how the scripting engine handles objects in memory.

CVE-2018-0893
MITRE

CVE Title: Scripting Engine Memory Corruption Vulnerability
Description:

A remote code execution vulnerability exists in the way that the 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 scripting engine handles objects in memory.

CVE Title: CNG Security Feature Bypass Vulnerability
Description:

A security feature bypass vulnerability exists in the Cryptography Next Generation (CNG) kernel-mode driver (cng.sys) when it fails to properly validate and enforce impersonation levels.

An attacker could exploit this vulnerability by convincing a user to run a specially crafted application that is designed to cause CNG to improperly validate impersonation levels, potentially allowing the attacker to gain access to information beyond the access level of the local user.

The security update addresses the vulnerability by correcting how the kernel-mode driver validates and enforces impersonation levels.

CVE Title: Microsoft Browser Information Disclosure Vulnerability
Description:

An information disclosure vulnerability exists when affected Microsoft browsers improperly handle objects in memory. An attacker who successfully exploited this 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 that is used to 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 security update addresses the vulnerability by modifying how Microsoft browsers handle objects in memory.

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 Browser Information Disclosure Vulnerability
Description:

An information disclosure vulnerability exists when affected Microsoft browsers improperly handle objects in memory. An attacker who successfully exploited this 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 that is used to 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 security update addresses the vulnerability by modifying how Microsoft browsers handle objects in memory.

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: 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: Scripting Engine Memory Corruption Vulnerability
Description:

A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. 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 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 the vulnerability.

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

CVE Title: Scripting Engine Information Disclosure Vulnerability
Description:

An information disclosure vulnerability exists when the scripting engine does not properly handle objects in memory in Microsoft Edge. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user’s system.

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 security update addresses the vulnerability by changing how the scripting engine handles objects in memory.
