Description

Multiple BSD OSs contain a flaw that may allow a malicious attacker to bypass firewall rulesets. The issue is triggered when a packet is sent with a unicast link-layer address that contains an IP broadcast address. It is possible that the flaw may allow a TCP connection to a broadcast address resulting in a loss of integrity.
