Multiple vulnerabilities were discovered and corrected in libtiff: Buffer overflow in LibTIFF allows remote attackers to execute arbitrary code or cause a denial of service via a crafted TIFF image with JPEG encoding . Heap-based buffer overflow in the thunder decoder in tif_thunder.c in LibTIFF 3.9.4 and earlier allows remote attackers to execute arbitrary code via crafted THUNDER_2BITDELTAS data in a .tiff file that has an unexpected BitsPerSample value . Packages for 2009.0 are provided as of the Extended Maintenance Program
