The remote Ubuntu host is missing a security-related patch.
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).
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 libtiff4 package.
