Detail

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.
