21 May 2013

tiff vulnerabilities

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

  • Ubuntu 13.04
  • Ubuntu 12.10
  • Ubuntu 12.04 LTS
  • Ubuntu 10.04 LTS

Summary

LibTIFF could be made to crash or run programs as your login if it opened a specially crafted file.

Software Description

  • tiff - Tag Image File Format (TIFF) library

Details

Emmanuel Bouillon discovered that LibTIFF incorrectly handled certain malformed images when using the tiff2pdf tool. If a user or automated system were tricked into opening a specially crafted TIFF image, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 13.04
libtiff5 - 4.0.2-4ubuntu2.1
Ubuntu 12.10
libtiff5 - 4.0.2-1ubuntu2.2
Ubuntu 12.04 LTS
libtiff4 - 3.9.5-2ubuntu1.5
Ubuntu 10.04 LTS
libtiff4 - 3.9.2-2ubuntu0.13

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

In general, a standard system update will make all the necessary changes.
