Details

Emmanuel Bouillon discovered that LibTIFF incorrectly handled certain
malformed images when using the tiff2pdf tool. 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.
