Description Huzaifa S. Sidhpurwala 2012-06-18 00:41:07 EDT
A type-conversion flaw leading to a heap-based buffer overflow was found in the way libtiff reads certain tiled tiff files. An attacker could create a specially-crafted TIFF image that, when opened, could cause an application using libtiff to crash or, possibly, execute arbitrary code with the privileges of the user running the application.

This issue does affects only version 3.x, but is fixed in upstream 4.x
