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.

The problem can be corrected by updating your system to the following
Ubuntu 16.04 LTS:
Ubuntu 14.04 LTS:
In general, a standard system update will make all the necessary changes.
