EulerOS 2.0 SP8 : xorg-x11-server (EulerOS-SA-2022-2484)

high Nessus Plugin ID 165856

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

 - A flaw was found in the Xorg-x11-server. An out-of-bounds access issue can occur in the ProcXkbSetGeometry function due to improper validation of the request length. (CVE-2022-2319)

 - A flaw was found in the Xorg-x11-server. The specific flaw exists within the handling of ProcXkbSetDeviceInfo requests. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. This flaw allows an attacker to escalate privileges and execute arbitrary code in the context of root. (CVE-2022-2320)

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.
