========================================================================== Ubuntu Security Notice USN-3606-1 March 26, 2018
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 16.04 LTS: libtiff-tools 4.0.6-1ubuntu0.4 libtiff5 4.0.6-1ubuntu0.4
Ubuntu 14.04 LTS: libtiff-tools 4.0.3-7ubuntu0.9 libtiff5 4.0.3-7ubuntu0.9
In general, a standard system update will make all the necessary changes.
