Amazon Linux 2 : gdk-pixbuf2, --advisory ALAS2-2026-3240 (ALAS-2026-3240)

high Nessus Plugin ID 306279

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of gdk-pixbuf2 installed on the remote host is prior to 2.36.12-3. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3240 advisory.

 A flaw was found in the gdk-pixbuf library. This heap-based buffer overflow vulnerability occurs in the JPEG image loader due to improper validation of color component counts when processing a specially crafted JPEG image. A remote attacker can exploit this flaw without user interaction, for example, via thumbnail generation. Successful exploitation leads to application crashes and denial of service (DoS) conditions.
 (CVE-2026-5201)

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 'yum update gdk-pixbuf2' or or 'yum update --advisory ALAS2-2026-3240' to update your system.
