CVE Title: Windows Kernel Elevation of Privilege Vulnerability
Description: An elevation of privilege vulnerability exists when the Windows kernel fails to properly handle 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 to take control of an affected system. The update addresses the vulnerability by correcting how the Windows kernel handles objects in memory. FAQ: None Mitigations: None Workarounds: None Revision: 1.0    2020-08-11T07:00:00Z     Information published. This CVE was addressed by updates that were released in July 2020, but the CVE was inadvertently omitted from the July 2020 Security Updates. This is an informational change only. Customers who have already installed the July 2020 update do not need to take any further action. |

CVE Title: Win32k Information Disclosure Vulnerability
Description: An information disclosure vulnerability exists when the win32k component improperly provides kernel information. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user’s system. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The security update addresses the vulnerability by correcting how win32k 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 memory layout - the vulnerability allows an attacker to collect information that facilitates predicting addressing of the memory. Mitigations: None Workarounds: None Revision: 1.0    2020-08-11T07:00:00Z     Information published. This CVE was addressed by updates that were released in June 2020, but the CVE was inadvertently omitted from the June 2020 Security Updates. This is an informational change only. Customers who have already installed the June 2020 update do not need to take any further action. |

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. FAQ: None Mitigations: None Workarounds: None Revision: 1.0    2020-08-11T07:00:00Z     Information published. |
