Cisco IOS Software Internet Key Exchange Version 2 Denial of Service
Vulnerability

Advisory ID: cisco-sa-20140326-ikev2

Revision 1.0

For Public Release 2014 March 26 16:00  UTC (GMT)

Summary
=======

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 free 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

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.
