  OpenSSH in most environments, they remain in use in others.

  It was found that gssftp, a Kerberos-aware FTP server, did not properly
  drop privileges. A remote FTP user could use this flaw to gain unauthorized
  read or write access to files that are owned by the root group.
  (CVE-2011-1526)

  Red Hat would like to thank the MIT Kerberos project for reporting this
  issue. Upstream acknowledges Tim Zingelman as the original reporter.

  All krb5-appl users should upgrade to these updated packages, which contain
  a backported patch to correct this issue.");
