- 漏洞描述

Check Point FireWall-1 contains a flaw that may allow a remote attacker to crash the firewall and cause it to "fail open". The issue is due to a flaw in the Getkey handling (inter-module communication protocol) which may allow for a buffer overflow. If an attacker supplies a specially crafted response to a Getkey request, they can crash the firewall. With such a request, the firewall daemon terminates leaving the ruleset enforcement enabled, but allows them to bypass any restriction outside of the standard policy enforcement.
