"The version of Autodesk SketchBook installed on the remote Mac OS X
host is Pro prior to 6.2.5 or Copic Edition prior to 2.0.2. It is,
therefore, affected by a heap-based buffer overflow vulnerability. The
flaw exists when decompressing RLE-compressed channel data in PSD
files, since user-supplied input is not correctly validated. Using a
specially crafted PSD file, an attacker could cause a denial of
service or execute arbitrary code.");
