Description Murray McAllister 2013-08-12 10:31:23 UTC 
A possible heap-based buffer overflow flaw was found in the readgifimage() function 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.
