Title

VPND IKE Fragment Reassembly - Heap Out-of-Bounds Write via Sequence Number Zero

Summary

The VPN service may mishandle an unexpected IKE fragment value received on the IKE port 500/UDP during the early stage of a connection attempt. This can cause the service to terminate unexpectedly, resulting in denial of service (temporary disruption of VPN-related functionality).

Severity

8.1 (High)
