Debian 11 DSA-5268-1 Critical: FFmpeg Denial of Service

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), this problem has been fixed in
version 7:4.3.5-0+deb11u1.

We recommend that you upgrade your ffmpeg packages.
