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.
