Security flaws in Libav on Ubuntu may lead to service interruptions or unauthorized code execution through manipulated media files. It is advisable to perform updates.
Libav could be made to crash or run programs as your login if it opened a specially crafted file.

Summary

Libav could be made to crash or run programs as your login if it opened a

specially crafted file.

Software Description:

- libav: Multimedia player, server, encoder and transcoder

Details:

It was discovered that Libav incorrectly handled certain malformed media

files. If a user were tricked into opening a crafted media 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.
