Title:	Cisco IOS Software and IOS XE Software Internet Key Exchange Version 2 Denial of Service Vulnerabilities
Summary:	Devices running Cisco IOS Software or IOS XE Software contain vulnerabilities within; the Internet Key Exchange (IKE) version 2 subsystem that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition.;; The vulnerabilities are due to how an affected device processes certain malformed IKEv2 packets. An attacker could exploit these vulnerabilities; by sending malformed IKEv2 packets to an affected device to be processed. A successful exploit could allow the attacker to cause a reload of the; affected device or excessive consumption of resources that would lead to a DoS condition. IKEv2 is automatically enabled on devices running Cisco; IOS and Cisco IOS XE Software when the Internet Security Association and Key Management Protocol (ISAKMP) is enabled. These vulnerabilities can only be triggered by sending malformed IKEv2 packets.;; There are no workarounds for the vulnerabilities described in this advisory. Cisco has released software updates that address these vulnerabilities.;; Note: The March 25, 2015, Cisco IOS & XE Software Security Advisory bundled publication includes seven Cisco Security Advisories.; The advisories address vulnerabilities in Cisco IOS Software and Cisco IOS XE Software. Individual publication links are in Cisco Event Response:; Semiannual Cisco IOS & XE Software Security Advisory Bundled Publication at the referenced link
