Amazon Linux 2023 : xorg-x11-server-common, xorg-x11-server-devel, xorg-x11-server-source (ALAS2023-2025-939)

high Nessus Plugin ID 234338

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2025-939 advisory.

 In X.Org X server 20.11 through 21.1.16, when a client application uses easystroke for mouse gestures, the main thread modifies various data structures used by the input thread without acquiring a lock, aka a race condition. In particular, AttachDevice in dix/devices.c does not acquire an input lock. (CVE-2022-49737)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'dnf update xorg-x11-server --releasever 2023.7.20250414' to update your system.
