It was discovered that FFmpeg did not correctly handle certain malformed Ogg Media (OGM) files. If a user were tricked into opening a crafted Ogg Media file, an attacker could cause the application using FFmpeg to crash, leading to a denial of service. (CVE-2008-4610)
It was discovered that FFmpeg did not correctly handle certain parameters when creating DTS streams. If a user were tricked into processing certain commands, 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. This issue only affected Ubuntu 8.10. (CVE-2008-4866)
