Detailsinfo

A vulnerability was found in Linux Kernel 2.6.19.0 (Operating System). It has been declared as critical. Affected by this vulnerability is some unknown functionality of the file drivers/net/tokenring/ibmtr.c. The manipulation with an unknown input leads to a denial of service vulnerability. The CWE definition for the vulnerability is CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. As an impact it is known to affect availability. The summary by CVE is:

The tr_rx function in ibmtr.c for Linux kernel 2.6.19 assigns the wrong flag to the ip_summed field, which allows remote attackers to cause a denial of service (memory corruption) via crafted packets that cause the kernel to interpret another field as an offset.

The issue has been introduced in 11/29/2006. The weakness was published 12/08/2006 by Al Viro with Kernel Team (Website). The advisory is shared at kernel.org. This vulnerability is known as CVE-2006-6333 since 12/06/2006. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are known, but no exploit is available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 7 days. During that time the estimated underground price was around $5k-$25k.

Applying a patch is able to eliminate this problem. The bugfix is ready for download at kernel.org.

The vulnerability is also documented in the databases at X-Force (30787), SecurityFocus (BID 21490†), OSVDB (31586†), Secunia (SA23254†) and Vulnerability Center (SBV-32072†). If you want to get the best quality for vulnerability data then you always have to consider VulDB.
