CESA-2024-0320: Important CentOS 7 xorg-x11-server

A series of critical security vulnerabilities have been identified in the X.Org server, notably affecting CentOS 7. These vulnerabilities, if exploited, could potentially allow for local privilege escalation, remote code execution, and cause the application to crash, severely compromising system security.

Overview of Vulnerabilities

CVE-2023-6816: This issue results from insufficient memory allocation when larger button values are used, leading to heap overflow.

CVE-2024-0229: An out-of-bounds memory access can occur when a device frozen by a synchronous grab is reattached to a different master. This can result in varying degrees of system compromise including remote code execution.

CVE-2024-0408: A flaw in the GLX PBuffer code could cause unlabeled resources to crash the XSELINUX module when accessed, posing a crash risk.

CVE-2024-0409: Incorrect private data type usage in cursor creation in Xephyr and Xwayland can overwrite XSELINUX context leading to potential crashes.

CVE-2024-21885: In XISendDeviceHierarchyEvent, adding new device IDs can exceed the allocated array lengths, risking heap buffer overflow and potential remote execution.

CVE-2024-21886: A heap buffer overflow can occur in the DisableDevice function, with similar risks of remote code execution and application crashes.
