CVE-2011-2896 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-2896):
  The LZW decompressor in the LWZReadByte function in giftoppm.c in the David
  Koblas GIF decoder in PBMPLUS, as used in the gif_read_lzw function in
  filter/image-gif.c in CUPS before 1.4.7, the LZWReadByte function in
  plug-ins/common/file-gif-load.c in GIMP 2.6.11 and earlier, the LZWReadByte
  function in img/gifread.c in XPCE in SWI-Prolog 5.10.4 and earlier, and
  other products, does not properly handle code words that are absent from the
  decompression table when encountered, which allows remote attackers to
  trigger an infinite loop or a heap-based buffer overflow, and possibly
  execute arbitrary code, via a crafted compressed stream, a related issue to
  CVE-2006-1168 and CVE-2011-2895.
