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
Summary:
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
Details:
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.
