  script_tag(name:"summary", value:"A vulnerability in the Internet Key Exchange Version 2 (IKEv2) module
  of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause
  a reload of the affected device that would lead to a denial of service (DoS) condition.

  The vulnerability is due to how an affected device processes certain malformed IKEv2 packets.
  An attacker could exploit this vulnerability by sending malformed IKEv2 packets to an affected
  device to be processed. An exploit could allow the attacker to cause a reload of the affected
  device that would lead to a DoS condition.

  Although IKEv2 is automatically enabled on Cisco IOS Software and Cisco IOS XE Software devices
  when the Internet Security Association and Key Management Protocol (ISAKMP) is enabled,
  the vulnerability can be triggered only by sending a malformed IKEv2 packet.

  Only IKEv2 packets can trigger this vulnerability.

  Cisco has released software updates that address this vulnerability. There are no workarounds to mitigate this vulnerability.

  Note: The March 26, 2014, Cisco IOS Software Security Advisory bundled publication includes six Cisco Security Advisories.
  All advisories address vulnerabilities in Cisco IOS Software. Each Cisco IOS Software Security Advisory lists the Cisco
  IOS Software releases that correct the vulnerability or vulnerabilities detailed in the advisory as well as the Cisco IOS
  Software releases that correct all Cisco IOS Software vulnerabilities in the March 2014 bundled publication.

  Individual publication links are in Cisco Event Response: Semiannual Cisco IOS Software Security Advisory Bundled Publication at the references.");
