  20. The remote host is missing the patch for the advisory MDKSA-2004:012 (XFree86).

  22.  
  23. Two buffer overflow vulnerabilities were found by iDEFENSE in XFree86's parsing
  24. of the font.alias file. The X server, which runs as root, fails to check the
  25. length of user-provided input; as a result a malicious user could craft a
  26. malformed font.alias file causing a buffer overflow upon parsing, which could
  27. eventually lead to the execution of arbitrary code.
  28. Additional vulnerabilities were found by David Dawes, also in the reading of
  29. font files.
  30. The updated packages have a patch from David Dawes to correct these
  31. vulnerabilities.
