• Ubuntu 8.04
• Ubuntu 7.10

Packages

• ffmpeg-debian -

Details

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)

It was discovered that FFmpeg did not correctly handle certain malformed
DTS Coherent Acoustics (DCA) files. If a user were tricked into opening a
crafted DCA 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. (CVE-2008-4867)

It was discovered that FFmpeg did not correctly handle certain malformed 4X
movie (4xm) files. If a user were tricked into opening a crafted 4xm file,
an attacker could execute arbitrary code with the privileges of the user
invoking the program. (CVE-2009-0385)
