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

- Ubuntu 16.04 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:

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 16.04 ESM:
   libtiff-tools                   4.0.6-1ubuntu0.8+esm8
   libtiff5                         4.0.6-1ubuntu0.8+esm8

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