Description Andrej Nemec 2016-10-27 08:35:56 UTC

An exploitable heap based buffer overflow exists in the handling of TIFF images in LibTIFF’s TIFF2PDF tool. A crafted TIFF document can lead to a heap based buffer overflow resulting in remote code execution. Vulnerability can be triggered via a saved TIFF file delivered by other means.
