Description Huzaifa S. Sidhpurwala 2013-08-13 04:29:55 EDT
An OOB Write was found in the LZW decompressor used in gif2tiff, a tool to convert GIF images to TIFF. A remote attacker could provide a specially-crafted GIF file that, when processed by gif2tiff, would cause gif2tiff to crash or, potentially, execute arbitrary code with the privileges of the user running gif2tiff.
