Ubuntu 11.10 / 12.04 LTS / 12.10 : libav vulnerabilities (USN-1705-1)

Ubuntu Security Notice (C) 2013-2016 Canonical, Inc. / NASL script (C) 2013-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

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.

Solution :

Update the affected libavcodec53 and / or libavformat53 packages.

Risk factor :

Critical / CVSS Base Score : 10.0
(CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 7.4
(CVSS2#E:U/RL:OF/RC:C)
Public Exploit Available : false
