Security readout for executives and security teams
A very old flaw (disclosed in 1999) in the Axent Raptor firewall let an attacker crash or disrupt the firewall by sending IP packets containing malformed zero-length IP options. In practical terms, someone on a network path could knock the firewall offline, interrupting business traffic. Axent Raptor is a legacy product no longer in mainstream use, so exposure today is limited to organizations still running end-of-life equipment. Exposure is confined to environments still operating Axent Raptor firewalls, a product line long past end-of-life (Axent was acquired by Symantec in 2000; the product was later rebranded and eventually discontinued). Modern enterprises are almost certainly not exposed. Any residual exposure would require the affected firewall to be reachable by packets carrying IP options. Low priority for modern enterprises. Only relevant if legacy Axent Raptor firewalls remain in use; in that case, plan replacement rather than patching, since the product is end-of-life. Mitigation focus: Retire any remaining Axent Raptor firewalls and migrate to a currently supported next-generation firewall.; Consult vendor (Symantec/Broadcom successor) guidance for legacy Raptor upgrade or replacement paths.; Block or drop IP packets carrying IP options at upstream routers where operationally feasible..
