  21. The remote host is missing the patch for the advisory MDKSA-2002:047 (util-linux).

  24. Michal Zalewski found a vulnerability in the util-linux package with the chfn
  25. utility. This utility allows users to modify some information in the /etc/passwd
  26. file, and is installed setuid root. Using a carefully crafted attack sequence,
  27. an attacker can exploit a complex file locking and modification race that would
  28. allow them to make changes to the /etc/passwd file. To successfully exploit this
  29. vulnerability and obtain privilege escalation, there is a need for some
  30. administrator interaction, and the password file must over over 4kb in size; the
  31. attacker's entry cannot be in the last 4kb of the file.
