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 (buster), this problem has been fixed
in version 7:4.1.9-0+deb10u1.

We recommend that you upgrade your ffmpeg packages.
