Detailsinfo

A vulnerability was found in Linux Kernel (Operating System). It has been rated as critical. Affected by this issue is an unknown code block. The manipulation with an unknown input leads to a authentication spoofing vulnerability. Using CWE to declare the problem leads to CWE-290. This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks. Impacted is integrity. CVE summarizes:

Linux kernel before 2.6.12 allows remote attackers to poison the bridge forwarding table using frames that have already been dropped by filtering, which can cause the bridge to forward spoofed packets.

The bug was discovered 11/22/2005. The weakness was disclosed 10/20/2005 (Website). The advisory is shared for download at ubuntulinux.org. This vulnerability is handled as CVE-2005-3272 since 10/20/2005. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 672 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 21997 (CentOS 4 : kernel (CESA-2006:0493)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS Local Security Checks and running in the context l.

Upgrading to version 2.6.12 eliminates this vulnerability. A possible mitigation has been published 8 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (21997), SecurityFocus (BID 15536†), OSVDB (21278†), Secunia (SA18056†) and Vulnerability Center (SBV-11673†). The entries VDB-1833, VDB-2134, VDB-2178 and VDB-2476 are pretty similar. Once again VulDB remains the best source for vulnerability data.
