critical Nessus Plugin ID 154772

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-4998 advisory.

Several vulnerabilities have been discovered in the FFmpeg multimedia framework, which could result in denial of service or potentially the execution of arbitrary code if malformed files/streams are processed.
For the stable distribution (bullseye), these problems have been fixed in version 7:4.3.3-0+deb11u1. We recommend that you upgrade your ffmpeg packages. For the detailed security status of ffmpeg please refer to its security tracker page at: https://security-tracker.debian.org/tracker/ffmpeg

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the ffmpeg packages.

For the stable distribution (bullseye), these problems have been fixed in version 7
