Echo: ffmpeg: security update to 7:7.1.5-0+deb13u1+e2

high Tenable Cloud Security Plugin ID 463969

Description

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

 - FFmpeg versions 2.1 through 8.1.2 contains a heap buffer overflow vulnerability in the VobSub subtitle
 demuxer that allows attackers to corrupt adjacent heap memory by supplying a malicious .sub/.idx subtitle
 file declaring more distinct stream IDs than the fixed-size array bounds in libavformat/mpeg.c. Attackers
 can craft a subtitle file with excessive distinct stream IDs to trigger unbounded writes beyond the
 vobsub->q[] array boundary via ff_subtitles_queue_insert(), potentially achieving arbitrary code execution
 in any application using FFmpeg's VobSub demuxer. (CVE-2026-64830)

Solution

Update the ffmpeg library and its related packages to version 7:7.1.5-0+deb13u1+e2 or later.
