EulerOS 2.0 SP10 : xorg-x11-server (EulerOS-SA-2025-1017)

high Nessus Plugin ID 214016

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 use-after-free flaw was found in xorg-x11-server-Xvfb. This issue occurs in Xvfb with 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 a screen 1 to a screen 0, a use-after-free issue may be triggered during shutdown or reset of the Xvfb server, allowing for possible escalation of privileges or denial of service.(CVE-2023-5574)

A flaw was found in the X.org server. Due to improperly tracked allocation size in _XkbSetCompatMap, a local attacker may be able to trigger a buffer overflow condition via a specially crafted payload, leading to denial of service or local privilege escalation in distributions where the X.org server is run with root privileges.(CVE-2024-9632)

Tenable has extracted the preceding description block directly from the EulerOS xorg-x11-server security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected xorg-x11-server packages.
