Tavis Ormandy and Andrey Kiselev discovered that libtiff did not sufficiently verify the validity of TIFF files. By tricking an user into opening a specially crafted TIFF file with any application that uses libtiff, an attacker could exploit this to crash the application or even execute arbitrary code with the application’s privileges.
