Synopsis

The remote EulerOS host is missing a security update.

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 vulnerability was found in X.Org. This issue occurs due to a dangling pointer in DeepCopyPointerClasses that can be exploited by ProcXkbSetDeviceInfo() and ProcXkbGetDeviceInfo() to read and write into freed memory. This can lead to local privilege elevation on systems where the X server runs privileged and remote code execution for ssh X forwarding sessions. (CVE-2023-0494)

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.
