Ubuntu Security Notice USN-3864-1
January 22, 2019

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

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

- Ubuntu 18.10
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

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 18.10:
libtiff-tools 4.0.9-6ubuntu0.1
libtiff5 4.0.9-6ubuntu0.1

Ubuntu 18.04 LTS:
libtiff-tools 4.0.9-5ubuntu0.1
libtiff5 4.0.9-5ubuntu0.1

Ubuntu 16.04 LTS:
libtiff-tools 4.0.6-1ubuntu0.5
libtiff5 4.0.6-1ubuntu0.5

Ubuntu 14.04 LTS:
libtiff-tools 4.0.3-7ubuntu0.10
libtiff5 4.0.3-7ubuntu0.10

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