It was discovered that LibTIFF incorrectly handled certain malformed images using the PixarLog compression format. If a user or automated system were tricked into opening a specially crafted TIFF image, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges.
(CVE-2012-4447)

Huzaifa S. Sidhpurwala discovered that the ppm2tiff tool incorrectly handled certain malformed PPM images. If a user or automated system were tricked into opening a specially crafted PPM image, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges.
(CVE-2012-4564).
