tag_summary = "This host has XnView installed and is prone to multiple heap based
  buffer overflow vulnerabilities.

  Vulnerabilities Insight:
  The flaws are due to
  - A signedness error in the FlashPix plugin (Xfpx.dll) when validating
    buffer sizes to process image's content.
  - An error when processing image data within Personal Computer eXchange
    (PCX) files.
  - A boundary error when parsing a directory, which allows attackers to cause a
    buffer overflow when browsing folder from an extracted archive file.";

tag_impact = "Successful exploitation will allow attackers to execute arbitrary code on the
  system via a specially crafted files or cause a denial of service condition.
  Impact Level: System/Application";
tag_affected = "XnView versions 1.98.5 and prior on windows";
tag_solution = "Update to XnView version 1.98.8 or later,
  For updates refer to http://www.xnview.com/";
