Id Description
5454 TCP Wrappers PARANOID Reverse DNS ACL Bypass

FreeBSD's distribution of tcp_wrappers contains a flaw that may allow a malicious user access to restricted network resources. The issue is triggered when a flawed check for a numeric result during reverse DNS lookup occurs. It is possible that the flaw may allow bypass of tcp_wrappers 'PARANOID' ACL restrictions.
