Ubuntu Security Notice USN-1511-1
19th July, 2012
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS
tiff2pdf could be made to crash or run programs as your login if it opened a specially crafted file.
- tiff - Tag Image File Format (TIFF) library
Huzaifa Sidhpurwala discovered that the tiff2pdf utility incorrectly
handled certain malformed TIFF images. 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.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 12.04 LTS:
- libtiff-tools 3.9.5-2ubuntu1.2
- Ubuntu 11.10:
- libtiff-tools 3.9.5-1ubuntu1.3
- Ubuntu 11.04:
- libtiff-tools 3.9.4-5ubuntu6.3
- Ubuntu 10.04 LTS:

- Ubuntu 8.04 LTS:
- libtiff-tools 3.8.2-7ubuntu3.13
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
