==========================================================================
Ubuntu Security Notice USN-4158-1
October 17, 2019

tiff vulnerabilities
==========================================================================

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

- Ubuntu 19.04
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in LibTIFF.

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 19.04:
  libtiff-tools                   4.0.10-4ubuntu0.1
  libtiff5                        4.0.10-4ubuntu0.1

Ubuntu 18.04 LTS:
  libtiff-tools                   4.0.9-5ubuntu0.3
  libtiff5                        4.0.9-5ubuntu0.3

Ubuntu 16.04 LTS:
  libtiff-tools                   4.0.6-1ubuntu0.7
  libtiff5                        4.0.6-1ubuntu0.7

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