USN-1102-1: tiff vulnerability

Releases

• Ubuntu 10.10
• Ubuntu 10.04
• Ubuntu 9.10
• Ubuntu 8.04
• Ubuntu 6.06

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

• libtiff4 - 3.8.2-13ubuntu0.6

Ubuntu 8.04

• libtiff4 - 3.8.2-7ubuntu3.9

Ubuntu 6.06

• libtiff4 - 3.7.4-1ubuntu3.11

Ubuntu 10.10

• libtiff4 - 3.9.4-2ubuntu0.3

Ubuntu 10.04

• libtiff4 - 3.9.2-2ubuntu0.6

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