Detailsinfo

A vulnerability was found in OpenBSD 3.x/4.0 (Operating System). It has been rated as critical. This issue affects an unknown part of the component IPv6 Type 0 Route Header Handler. The manipulation with an unknown input leads to a denial of service vulnerability. Using CWE to declare the problem leads to CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. Impacted is availability. The summary by CVE is:

The IPv6 protocol allows remote attackers to cause a denial of service via crafted IPv6 type 0 route headers (IPV6_RTHDR_TYPE_0) that create network amplification between two routers.

The weakness was released 04/24/2007 by Philippe Biondi and Arnaud Ebalard with OpenBSD (Website). The advisory is shared at secdev.org. The identification of this vulnerability is CVE-2007-2242 since 04/25/2007. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 30142 (openSUSE 10 Security Update : kernel (kernel-4929)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 156097 (Oracle Enterprise Linux Update for Kernel (ELSA-2007-0347)).

Upgrading eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at openbsd.org. The best possible mitigation is suggested to be upgrading to the latest version. A possible mitigation has been published 5 months after the disclosure of the vulnerability.
