  GD Graphics Library 2.x, does not properly verify a certain colorsTotal
  structure member, which might allow remote attackers to conduct
  buffer overflow or buffer over-read attacks via a crafted GD file,
  a different vulnerability than CVE-2009-3293.  NOTE: some of these
  details are obtained from third party information (CVE-2009-3546).
