  21. The remote host is missing the patch for the advisory MDKSA-2003:017-1 (pam).

  24. Andreas Beck discovered that the pam_xauth module would forward authorization
  25. information from the root account to unprivileged users. This can be exploited
  26. by a local attacker to gain access to the root user's X session. In order for it
  27. to be successfully exploited, the attacker would have to somehow get the root
  28. user to su to the account belonging to the attacker.
  29. Update:
  30. The previous fix was incorrect because certain applications, such as userdrake
  31. and net_monitor could not be executed as root, although they could be executed
  32. as users who successfully authenticated as root.
