USN-330-1: tiff vulnerabilities

Publication date

Overview

tiff vulnerabilities


Details

Tavis Ormandy discovered that the TIFF library did not sufficiently
check handled images for validity. By tricking an user or an automated
system into processing a specially crafted TIFF image, an attacker
could exploit these weaknesses to execute arbitrary code with the
target application's privileges.

This library is used in many client and server applications, thus you
should reboot your computer after the upgrade to ensure that all
running programs use the new version of the library.
