Ubuntu 12.04 LTS : libav vulnerabilities (USN-2309-1)

Medium Nessus Plugin ID 77146


The remote Ubuntu host is missing one or more security-related patches.


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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected libavcodec53 and / or libavformat53 packages.
