Technical details
A null pointer dereference vulnerability exists in Microsoft Windows IKE Extension that can be triggered by a network-based attacker without authentication. The vulnerability allows an attacker to send specially crafted network packets that cause the IKE extension to dereference a null pointer, resulting in a denial of service condition. The affected component is reachable over the network and does not require user interaction. An attacker can repeatedly trigger this crash to sustain a denial of service attack against the target system. Patches are expected from Microsoft as part of standard security updates.
