Echo: ffmpeg: security update to 7:7.1.5-0+deb13u1+e5

high Tenable Self-Hosted Container Security Plugin ID 459081

Description

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

 - FFmpeg through 8.1.2, fixed in commit b506faf, contains a heap out-of-bounds write vulnerability in the
 native PNG and APNG encoders that allows remote attackers to corrupt heap memory by supplying a crafted
 PNG image with a malicious eXIf chunk. Attackers can craft an eXIf chunk where multiple IFD entries
 reference the same large value payload, causing canonical serialization to expand the output far beyond
 the undersized allocation estimated by add_exif_profile_size(), resulting in png_write_chunk() writing
 tens of thousands of bytes past the buffer boundary, leading to deterministic heap corruption, process
 crash, and potentially arbitrary code execution. (CVE-2026-66040)

Solution

Update the ffmpeg library and its related packages to version 7:7.1.5-0+deb13u1+e5 or later.
