USN-3906-2: LibTIFF vulnerabilities

Releases

• Ubuntu 12.04

Packages

• 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

• libtiff4 - 3.9.5-2ubuntu1.12
• libtiff-tools - 3.9.5-2ubuntu1.12

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