USN-3212-2: LibTIFF regression

Releases

• Ubuntu 16.10
• Ubuntu 16.04 ESM
• Ubuntu 14.04 ESM

Packages

• tiff - Tag Image File Format (TIFF) library

Details

USN-3212-1 fixed vulnerabilities in LibTIFF. Unfortunately, some of the
security patches were misapplied, which caused a regression when processing
certain images. This update fixes the problem.

We apologize for the inconvenience.

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 16.10

• libtiff-tools - 4.0.6-2ubuntu0.2
• libtiff5 - 4.0.6-2ubuntu0.2

Ubuntu 16.04

• libtiff-tools - 4.0.6-1ubuntu0.2
• libtiff5 - 4.0.6-1ubuntu0.2

Ubuntu 14.04

• libtiff-tools - 4.0.3-7ubuntu0.7
• libtiff5 - 4.0.3-7ubuntu0.7

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