Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.04

Summary:

If a user were tricked into opening a crafted ogg 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-2011-1196)

It was discovered that Libav incorrectly handled certain malformed AMV files. If a user were tricked into opening a crafted AMV 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-2011-1931)

Emmanouel Kellinis discovered that Libav incorrectly handled certain malformed CAVS files. If a user were tricked into opening a crafted CAVS 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-2011-3362)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 11.04:
libavcodec52 4:0.6.2-1ubuntu1.1
