Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (3.78%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

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.
