tiff vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 10.10
  • Ubuntu 10.04 LTS

Summary

The TIFF library could be made to run programs as your login if it opened a specially crafted file.

Software Description

  • tiff - TIFF manipulation and conversion tools

Details

It was discovered that the TIFF library incorrectly handled certain JPEG data. 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 10.10
libtiff4 - 3.9.4-2ubuntu0.4
Ubuntu 10.04 LTS
libtiff4 - 3.9.2-2ubuntu0.7

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

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