  As confirmed by the vendor, a Denial of Service (DoS) vulnerability
  exists in the PNG [0] image format library libpng [1], versions 1.0.6
  through 1.2.12 and 1.0.20. The bug is in the decoder for the sPLT
  ("suggested palette") chunk and can lead to crashes and, accordingly,
  a DoS, when an application using libpng for PNG processing displays a
  specially crafted PNG image. The Common Vulnerabilities and Exposures
  (CVE) project assigned the id CVE-2006-5793 [2] to the problem.
