  21. The remote host is missing the patch for the advisory MDKSA-2004:099 (XFree86).
  22.  
  23.  
  24. Chris Evans found several stack and integer overflows in the libXpm code of
  25. X.Org/XFree86:
  26. Stack overflows (CAN-2004-0687):
  27. Careless use of strcat() in both the XPMv1 and XPMv2/3 xpmParseColors code leads
  28. to a stack based overflow (parse.c).
  29. Stack overflow reading pixel values in ParseAndPutPixels (create.c) as well as
  30. ParsePixels (parse.c).
  31. Integer Overflows (CAN-2004-0688):
  32. Integer overflow allocating colorTable in xpmParseColors (parse.c) - probably a
  33. crashable but not exploitable offence.
  34. The updated packages have patches from Chris Evans and Matthieu Herrb to address
  35. these vulnerabilities.
