- 漏洞描述

IPFilter contains a flaw that may allow a remote attacker to bypass the ruleset. The issue is due to the presence of overlapping rules that relate to "return-rst" and "keep state". These two rules create a race condition that may allow an attacker to send the right sequence of packets to win, allowing them to bypass the filter rules completely.
