Debian: DSA-5721-1 Critical: FFmpeg Denial Of Service & Code Execution

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 oldstable distribution (bullseye), these problems have been fixed
in version 7:4.3.7-0+deb11u1.

We recommend that you upgrade your ffmpeg packages.
