Chainguard: multiple ffmpeg-cuda-fips-8.1 packages: security update to 8.1.3-r0

medium Tenable Self-Hosted Container Security Plugin ID 476654

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-cuda-fips-8.1 library and its related packages to version 8.1.3-r0 or later.
