  script_tag(name:"summary", value:"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:
