- 漏洞描述

Check Point VPN-1/FireWall-1 contains a flaw that may allow a remote attacker to bypass the ruleset. The issue is due to the firewall not properly filtering specially fragmented TCP connections that will bypass the directionality checks implemented. If an attacker sends the right requests by closing and reopening one-way connections, they may be able to initiate traffic otherwise denied.
