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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 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.

BiLateral Transit Agreements?
by Jack Bates 26 Mar '14

26 Mar '14

Does anyone have experience with BiLateral Transit Agreements, compared to the same with Peering Agreements? I have 2 ISP customers that are looking at such an agreement. While I can modify the standard BLPA templates to support transit provisions, I was curious if anyone had done so and what pitfalls to look for or considerations that should be made. Our particular case is high cost transport, so both companies are looking at each having a Tier 1 transit and then supporting the second through their agreement. Jack Bates

auDA has announced it will be introducing DNSSEC into the .au domain space in an experimental capacity. Deployment on production servers will commence during April and will be trialled for 4 months. The .au DS records will_not be added to the root zone during this period. Operators should_not create or implement trust anchors for .au in their production environments during this experimental phase. A mailing list has been created for all future announcements related to DNSSEC in .au, if you wish to subscribe to this mailing list please visit http://www.lists.auda.org.au/mailman/listinfo/dnssec-announce For further information about the implementation of DNSSEC in .au please see http://www.auda.org.au/industry-information/au-domains/dnssec/.

I am opposed to them, assuming that the election process is open and honest and the voters have an opportunity to be informed. (And if it is not, THAT is what needs to be fixed.) It is my opinion that every discussion of the "need" for term limits involves a person or group of people who have these important characteristics: They propose and vote in favor of legislation or do something else the term-limiters don't like. Their constituency DOES like what they do and signal that by re-electing them. State Senator Ernie Chambers here in Nebraska should be the text-book example of the evils of term limits. -- Requiescas in pace o email Two identifying characteristics of System Administrators: Ex turpi causa non oritur actio Infallibility, and the ability to learn from their mistakes.

How robust is the V6 to V4 infrastructure?
by Naslund, Steve 25 Mar '14

25 Mar '14

A question came to mind with all the discussion of ipv6 vulnerabilities. I am wondering for those with a lot of real world pure IPv6 connectivity, how robust have been the V6 to V4 gateways necessary for intercommunication between native IPv6 hosts and the IPv4 world? I was thinking that going to native ipv6 depends heavily on these gateways being reachable and having fairly high performance characteristics. How are the service providers doing providing these services? Steven Naslund Chicago IL
