USN-1102-1: tiff vulnerability

04 April 2011

Certain applications could be made to run programs as your login if they opened a specially crafted TIFF file.

Releases

Packages

  • tiff - TIFF manipulation and conversion tools

Details

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.

Update instructions

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

Ubuntu 9.10
Ubuntu 8.04
Ubuntu 6.06
Ubuntu 10.10
Ubuntu 10.04

After a standard system update you need to restart your session to make
all the necessary changes.
