FFmpeg 0.5 < 9.0 Multiple Vulnerabilities
high Nessus Plugin ID 335156
Synopsis
The remote host is affected by multiple vulnerabilities.Description
The version of FFmpeg installed on the remote host is 0.5 or later but prior to 9.0. It is, therefore, affected by multiple vulnerabilities:- A signed integer overflow vulnerability in the DVB subtitle parser in libavcodec/dvbsub_parser.c allows attackers to trigger a heap buffer overflow by supplying a crafted WTV file, resulting in an out-of-bounds heap write and potential memory corruption or code execution. (CVE-2026-70628)
- An uninitialized heap memory disclosure vulnerability in the native TIFF decoder in libavcodec/tiff.c allows attackers to expose stale heap data by supplying a crafted TIFF file with a Deflate-compressed strip that produces fewer bytes than declared. (CVE-2026-70631)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade to FFmpeg version 9.0 or later.See Also
