This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.
The TCP implementation in (1) Linux, (2) platforms based on BSD Unix, (3) Microsoft Windows, (4) Cisco products, and probably other operating systems allows remote attackers to cause a denial of service (connection queue exhaustion) via multiple vectors that manipulate information in the TCP state table, as demonstrated by sockstress.

The impact of this vulnerability has yet to be determined. The full list of affected platforms is subject to change. The NVD will continue to monitor this vulnerability and adjust the configurations as needed.
The attacks reported by Outpost24 AB target the design limitations of the TCP protocol. Due to upstreams decision not to release updates, Red Hat do not plan to release updates to resolve these issues however, the effects of these attacks can be reduced via the mitigation methods as written in http://kbase.redhat.com/faq/docs/DOC-18730.
