Vulnerability Summary for CVE-2008-4609

Original release date:10/20/2008

Last revised:11/24/2009

Source: US-CERT/NIST

Overview

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.

Vendor Statements (disclaimer)

Official Statement from Red Hat (09/08/2009)

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.
