Echo: gst-plugins-bad1.0: security update to 1.26.2-3+deb13u2

medium Tenable Self-Hosted Container Security Plugin ID 458918

Description

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

 - An out-of-bounds write vulnerability was found in GStreamer's H.266/VVC PPS picture partition parser in
 gst-plugins-bad. In the multi-slice-in-tile processing of gst_h266_parser_parse_picture_partition()
 (gsth266parser.c), the loop iterates without checking that the slice index stays within bounds, writing
 past three fixed-size arrays (slice_height_in_ctus, slice_top_left_ctu_x, slice_top_left_ctu_y) in the
 GstH266PPS structure. While the initial proof-of-concept demonstrated a 4-byte out-of-bounds write, the
 code permits larger writes across multiple iterations. A crafted H.266/VVC media file can trigger this
 vulnerability. (CVE-2026-53701)

Solution

Update the gst-plugins-bad1.0 library and its related packages to version 1.26.2-3+deb13u2 or later.
