USN-3212-2: LibTIFF regression | Ubuntu security notices

Packages

tiff - Tag Image File Format (TIFF) library

Details

USN-3212-1 fixed vulnerabilities in LibTIFF. Unfortunately, some of the
security patches were misapplied, which caused a regression when processing
certain images. This update fixes the problem.

We apologize for the inconvenience.

Original advisory 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.
