Ubuntu Security Notice USN-1832-1
21st May, 2013
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS
LibTIFF 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
Emmanuel Bouillon discovered that LibTIFF incorrectly handled certain
malformed images when using the tiff2pdf tool. 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 13.04:
- libtiff5 4.0.2-4ubuntu2.1
- Ubuntu 12.10:
- libtiff5 4.0.2-1ubuntu2.2
- Ubuntu 12.04 LTS:
- libtiff4 3.9.5-2ubuntu1.5
- Ubuntu 10.04 LTS:
- libtiff4 3.9.2-2ubuntu0.13
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.
