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.
