Several security issues were fixed in LibTIFF.

Software Description: - tiff: Tag Image File Format (TIFF) library


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.

Ubuntu 19.04:
libtiff-tools 4.0.10-4ubuntu0.1
libtiff5 4.0.10-4ubuntu0.1

Ubuntu 18.04 LTS:

Ubuntu 16.04 LTS:
