tiff vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 17.10
– 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 17.10:
libtiff-tools 4.0.8-5ubuntu0.1
libtiff5 4.0.8-5ubuntu0.1

Ubuntu 14.04 LTS:
