Echo: gst-plugins-bad1.0: security update to 1.26.2-3+deb13u3

medium Tenable Self-Hosted Container Security Plugin ID 463346

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A flaw was found in GStreamer's gst-plugins-bad package. When processing a specially crafted H.264 video
 file containing malformed MVC or SVC extension slice NAL units, a 1-byte heap out-of-bounds read can occur
 during parsing. This happens when the parser attempts to check slice boundary information without first
 verifying that the NAL unit contains enough data beyond the extension header. An attacker could exploit
 this by tricking a user into opening a malicious H.264 video file, potentially causing the application to
 crash or leak a single byte of heap memory. (CVE-2026-12892)

Solution

Update the gst-plugins-bad1.0 library and its related packages to version 1.26.2-3+deb13u3 or later.
