Echo: ffmpeg: security update to 7:7.1.5-0+deb13u1+e3

high Tenable Cloud Security Plugin ID 457782

Description

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

 - FFmpeg through 8.1.2 contains an out-of-bounds write vulnerability that allows attackers to cause heap
 corruption by supplying a crafted ffconcat file processed with the -safe 0 flag. The TY demuxer's
 demux_audio() function decrements packet size without bounds checking, producing a negative size value
 that is passed to memcpy() in shorten_decode_frame(), where conversion to size_t wraps the value to near
 SIZE_MAX and triggers reads beyond the source allocation and writes far beyond the Shorten decoder's
 bitstream buffer. (CVE-2026-65704)

Solution

Update the ffmpeg library and its related packages to version 7:7.1.5-0+deb13u1+e3 or later.
