CVE-2013-4243: Buffer Overflow
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.
Other sources
Heap-based buffer overflow in the readgifimage function in the gif2tiff tool in libtiff 4.0.3 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted height and width values in a GIF image.
