"Steve Manzuik discovered that Libav incorrectly handled certain
malformed Matroska files. If a user were tricked into opening a
crafted Matroska 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. This issue only affected
Ubuntu 11.04. (CVE-2011-3504)

Phillip Langlois discovered that Libav incorrectly handled certain
malformed QDM2 streams. If a user were tricked into opening a crafted
QDM2 stream 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-2011-4351)

Phillip Langlois discovered that Libav incorrectly handled certain
malformed VP3 streams. If a user were tricked into opening a crafted
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-2011-4352)

Phillip Langlois discovered that Libav incorrectly handled certain
malformed VP5 and VP6 streams. If a user were tricked into opening a
crafted 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-2011-4353)

It was discovered that Libav incorrectly handled certain malformed VMD
files. If a user were tricked into opening a crafted VMD 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-2011-4364)

Phillip Langlois discovered that Libav incorrectly handled certain
malformed SVQ1 streams. If a user were tricked into opening a crafted
SVQ1 stream 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-2011-4579).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
