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

medium Tenable Cloud Security Plugin ID 455425

Description

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

 - FFmpeg versions from 0.5 up to, but not including, 9.0 contain an uninitialized heap memory disclosure
 vulnerability in the native TIFF decoder in libavcodec/tiff.c. An attacker who can cause FFmpeg to decode
 a crafted TIFF file can supply a valid Deflate-compressed strip that terminates successfully after
 producing fewer bytes than the declared strip requires. The tiff_unpack_zlib() function allocates a heap
 buffer sized for the full declared strip but copies all declared rows via memcpy() regardless of how many
 bytes zlib actually decompressed, causing unwritten bytes that can contain stale data from prior heap
 allocations to be incorporated into decoded image output and potentially exposing sensitive data in
 persistent services. (CVE-2026-70631)

Solution

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