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

medium Tenable Self-Hosted Container Security Plugin ID 465597

Description

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

 - A flaw was found in the GStreamer gst-plugins-bad package. When processing a malformed H.266/VVC video
 stream with a crafted aspect ratio indicator value, the H.266 parser performs an out-of-bounds read of up
 to 8 bytes from adjacent memory. This flaw allows an attacker to craft a malicious H.266 video file or
 stream that, when processed by a GStreamer-based application, could leak limited memory contents through
 video metadata, potentially exposing sensitive information from the application's address space.
 (CVE-2026-12891)

Solution

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