Azure Linux 3.0 Security Update: xorg-x11-server / xorg-x11-server-Xwayland (CVE-2025-49175)

medium Nessus Plugin ID 244790

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of xorg-x11-server / xorg-x11-server-Xwayland installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-49175 advisory.

 - A flaw was found in the X Rendering extension's handling of animated cursors. If a client provides no cursors, the server assumes at least one is present, leading to an out-of-bounds read and potential crash.
 (CVE-2025-49175)

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.
