Summary
xorg-server, xwayland regression
Details

USN-6587-1 fixed vulnerabilities in X.Org X Server. The fix was incomplete resulting in a possible regression. This update fixes the problem.

Original advisory details:

Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled memory when processing the DeviceFocusEvent and ProcXIQueryPointer APIs. An attacker could possibly use this issue to cause the X Server to crash, obtain sensitive information, or execute arbitrary code. (CVE-2023-6816)

Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled reattaching to a different master device. An attacker could use this issue to cause the X Server to crash, leading to a denial of service, or possibly execute arbitrary code. (CVE-2024-0229)

Olivier Fourdan and Donn Seeley discovered that the X.Org X Server incorrectly labeled GLX PBuffers when used with SELinux. An attacker could use this issue to cause the X Server to crash, leading to a denial of service. (CVE-2024-0408)

Olivier Fourdan discovered that the X.Org X Server incorrectly handled the curser code when used with SELinux. An attacker could use this issue to cause the X Server to crash, leading to a denial of service. (CVE-2024-0409)

Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled memory when processing the XISendDeviceHierarchyEvent API. An attacker could possibly use this issue to cause the X Server to crash, or execute arbitrary code. (CVE-2024-21885)

Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled devices being disabled. An attacker could possibly use this issue to cause the X Server to crash, or execute arbitrary code. (CVE-2024-21886)
