Ubuntu Security Notice USN-3212-2
May 30, 2017

tiff regression
==========================================================================

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

- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

USN-3212-1 caused a regression in LibTIFF.

Software Description:
- 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 LTS:
libtiff-tools 4.0.6-1ubuntu0.2
libtiff5 4.0.6-1ubuntu0.2

Ubuntu 14.04 LTS:
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.
