USN-3864-1: LibTIFF vulnerabilities

Releases

• Ubuntu 18.10
• Ubuntu 18.04 ESM
• Ubuntu 16.04 ESM
• Ubuntu 14.04 ESM

Packages

• 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

• libtiff-tools - 4.0.9-5ubuntu0.1

Ubuntu 16.04

Ubuntu 14.04

• 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.
