Buffer overflow in the Internet Key Exchange version 1 (IKEv1) implementation in Symantec Dynamic VPN Services, as used in Enterprise Firewall, Gateway Security, and Firewall /VPN Appliance products, allows remote attackers to cause a denial of service and possibly execute arbitrary code via crafted IKE packets, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1.

Security readout for executives and security teams

This is an old Symantec VPN/firewall flaw in IKEv1 handling. A remote attacker could send crafted VPN negotiation traffic that may crash the service and could possibly run code. Business urgency depends on whether legacy Symantec Enterprise Firewall, Gateway Security, or Firewall/VPN Appliance products remain deployed. Exposure is likely limited to legacy Symantec Dynamic VPN Services deployments in Enterprise Firewall, Gateway Security, and Firewall/VPN Appliance products. The bundle does not provide exact affected versions or CPEs, so asset confirmation is required. Treat as high priority only if legacy Symantec VPN/firewall products remain in use. The core risk is disruption of remote access or firewall services, with possible code execution. If those products are absent, risk is minimal. Mitigation focus: Identify any deployed Symantec Dynamic VPN Services or named Symantec firewall/VPN products.; Review Symantec’s advisory for product-specific fixes, workarounds, and affected versions.; Disable or limit IKEv1 VPN exposure where operationally feasible..
