Cesar Bernardini and Felipe Andres Manzano discovered that FFmpeg incorrectly handled certain malformed flic files. If a user were tricked into opening a crafted flic file, an attacker could cause a denial of service via application crash, or possibly execute arbitrary code with the privileges of the user invoking the program.
