EulerOS 2.0 SP11 : xorg-x11-server (EulerOS-SA-2024-1131)

high Nessus Plugin ID 189701

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the xorg-x11-server package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - A out-of-bounds write flaw was found in the xorg-x11-server. This issue occurs due to an incorrect calculation of a buffer offset when copying data stored in the heap in the XIChangeDeviceProperty function in Xi/xiproperty.c and in RRChangeOutputProperty function in randr/rrproperty.c, allowing for possible escalation of privileges or denial of service. (CVE-2023-5367)

 - A use-after-free flaw was found in the xorg-x11-server. An X server crash may occur in a very specific and legacy configuration (a multi-screen setup with multiple protocol screens, also known as Zaphod mode) if the pointer is warped from within a window on one screen to the root window of the other screen and if the original window is destroyed followed by another window being destroyed. (CVE-2023-5380)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected xorg-x11-server packages.
