- 漏洞描述

Check Point VPN-1/FireWall-1 contains a flaw that may allow a remote attacker to send traffic that bypasses the ruleset. The issue is due to a flaw in the FWZ client processing that may allow spoofed packets through despite anti-spoofing checks being present. If an attacker sends specially crafted packets encapsulated as FWZ packets, the firewall may let them pass.
