Description

A vulnerability in the IKEv2 feature of Cisco IOS Software, IOS XE Software, Secure Firewall ASA Software, and Secure FTD Software could allow an unauthenticated, remote attacker to cause the device to reload, resulting in a DoS condition.

A successful exploit could allow the attacker to cause an infinite loop that exhausts resources and could cause the device to reload.
