tiff vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS


Programs that use LibTIFF could be made to crash or run programs if they
opened a specially crafted file.

Software Description:
- tiff: Tag Image File Format (TIFF) library


It was discovered that LibTIFF incorrectly handled certain malformed
images using the DOTRANGE tag. 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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
  libtiff4                        3.9.5-2ubuntu1.4

Ubuntu 11.10:
  libtiff4                        3.9.5-1ubuntu1.5

Ubuntu 10.04 LTS:
  libtiff4                        3.9.2-2ubuntu0.12

Ubuntu 8.04 LTS:
  libtiff4                        3.8.2-7ubuntu3.16

In general, a standard system update will make all the necessary changes.
