USN-1102-1: tiff vulnerability

Publication date

4 April 2011

Overview

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


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.
