Description: The remote host is missing an update to tiff announced via advisory USN-1102-1.
Details follow:
Martin Barbella discovered that the thunder (aka ThunderScan) decoder in the TIFF library incorrectly handled an unexpected BitsPerSample value. 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.
Solution: The problem can be corrected by upgrading your system to the following package versions:
Ubuntu 6.06 LTS: libtiff4 3.7.4-1ubuntu3.11
Ubuntu 8.04 LTS: libtiff4 3.8.2-7ubuntu3.9
Ubuntu 9.10: libtiff4 3.8.2-13ubuntu0.6
Ubuntu 10.04 LTS: libtiff4 3.9.2-2ubuntu0.6
Ubuntu 10.10: libtiff4 3.9.4-2ubuntu0.3
After a standard system update you need to restart your session to make all the necessary changes.
