CVE-2009-1184 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-1184):
  The selinux_ip_postroute_iptables_compat function in
  security/selinux/hooks.c in the SELinux subsystem in the Linux kernel
  before 2.6.27.22, and 2.6.28.x before 2.6.28.10, when compat_net is
  enabled, omits calls to avc_has_perm for the (1) node and (2) port,
  which allows local users to bypass intended restrictions on network
  traffic.  NOTE: this was incorrectly reported as an issue fixed in
  2.6.27.21.
