TencentOS Server 4: xorg-x11-server-Xwayland (TSSA-2024:0667)

high Nessus Plugin ID 239142

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2024:0667 advisory.

Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

CVE-2023-1393:
A flaw was found in X.Org Server Overlay Window. A Use-After-Free may lead to local privilege escalation.
If a client explicitly destroys the compositor overlay window (aka COW), the Xserver would leave a dangling pointer to that window in the CompScreen structure, which will trigger a use-after-free later.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

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

Solution

Update the affected packages.
