CVE-2012-1174 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-1174):
  The rm_rf_children function in util.c in the systemd-logind login manager in
  systemd before 44, when logging out, allows local users to delete arbitrary
  files via a symlink attack on unspecified files, related to "particular
  records related with user session."
