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

  • Ubuntu 12.04 ESM

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

USN-3906-1 and USN-3864-1 fixed several vulnerabilities in LibTIFF. This update provides the corresponding update for Ubuntu 12.04 ESM.

Original advisory details:

It was discovered that LibTIFF incorrectly handled certain malformed images. If a user or automated system were tricked into opening a specially crafted 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 12.04 ESM
libtiff-tools - 3.9.5-2ubuntu1.12
libtiff4 - 3.9.5-2ubuntu1.12
