Problem Description:

+

As part of its stateful TCP connection tracking implementation, + pf performs sequence number validation on inbound packets. This + makes it difficult for a would-be attacker to spoof the sender and + inject packets into a TCP stream, since crafted packets must contain + sequence numbers which match the current connection state to avoid + being rejected by the firewall.

+

A bug in the implementation of sequence number validation means + that the sequence number is not in fact validated, allowing an + attacker who is able to impersonate the remote host and guess the + connection's port numbers to inject packets into the TCP stream.

+

Impact:

+

An attacker can, with relatively little effort, inject packets + into a TCP stream destined to a host behind a pf firewall. This + could be used to implement a denial-of-service attack for hosts + behind the firewall, for example by sending TCP RST packets to the + host.
