CBL Mariner 2.0 Security Update: xorg-x11-server (CVE-2023-1393)

high Nessus Plugin ID 201765

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of xorg-x11-server installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-1393 advisory.

 - 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.
 (CVE-2023-1393)

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.
