"This update to ffmpeg disables support for over 100 codecs, decoders,
and formats that are rarely used nowadays, for which the support
available in squeeze is most likely insufficient, etc.

This update is only meant to reduce the attack surface.

ffmpeg is otherwise unsupported in squeeze-lts, and any use of it with
untrusted data is highly discouraged.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
