Amazon Linux 2 : gstreamer1-plugins-bad-free, --advisory ALAS2-2026-3222 (ALAS-2026-3222)

high Nessus Plugin ID 304591

Synopsis

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

Description

The version of gstreamer1-plugins-bad-free installed on the remote host is prior to 1.18.4-5. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3222 advisory.

GStreamer JPEG Parser Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the processing of Huffman tables. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. (CVE-2026-3082)

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 gstreamer1-plugins-bad-free' or or 'yum update --advisory ALAS2-2026-3222' to update your system.
