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

medium Tenable Cloud Security Plugin ID 465216

Description

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

- FFmpeg versions from 3.0 up to, but not including, 9.0 contain an uninitialized heap memory read
vulnerability in the native RSCC decoder (libavcodec/rscc.c) that allows attackers to disclose heap memory
contents by supplying a crafted video file with a compressed tile that decompresses fewer bytes than the
declared tile geometry requires. When rscc_decode_frame() calls av_image_copy_plane() without validating
the decompressed byte count against the tile dimensions, the unwritten suffix of the persistent
intermediate buffer ctx->inflated_buf is copied into the decoded frame, potentially exposing data from
prior heap allocations or previous decoded frames in persistent decoding services. (CVE-2026-70629)

Solution

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