Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

Alexander Gavrun discovered that the TIFF library incorrectly
allocated space for a tile. If a user or automated system were tricked
into opening a specially crafted TIFF image, a remote attacker could
execute arbitrary code with user privileges, or crash the application,
leading to a denial of service. (CVE-2012-1173)

It was discovered that the tiffdump utility incorrectly handled
directory data structures with many directory entries. If a user or
automated system were tricked into opening a specially crafted TIFF
image, a remote attacker could crash the application, leading to a
denial of service, or possibly execute arbitrary code with user
privileges. This issue only applied to Ubuntu 8.04 LTS, Ubuntu 10.04
LTS, Ubuntu 10.10 and Ubuntu 11.04. (CVE-2010-4665).
