flac vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

FLAC could be made to crash or run programs as your login if it opened a
specially crafted file.

Software Description:
- flac: Free Lossless Audio Codec


It was discovered that FLAC incorrectly handled encoding certain files. A
remote attacker could use this issue to cause FLAC to crash, resulting in a
denial of service, or possibly execute arbitrary code.
