Detailsinfo

A vulnerability classified as problematic has been found in Linux Kernel up to 2.6.22 (Operating System). Affected is an unknown code of the component MSR Clearing Handler. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on availability. CVE summarizes:

The signal handling in the Linux kernel before 2.6.22, including 2.6.2, when running on PowerPC systems using HTX, allows local users to cause a denial of service via unspecified vectors involving floating point corruption and concurrency, related to clearing of MSR bits.

The bug was discovered 06/25/2007. The weakness was presented 07/09/2007 with Linux Kernel Team (Website). The advisory is shared for download at kernel.org. This vulnerability is traded as CVE-2007-3107 since 06/07/2007. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 14 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 67537 (Oracle Linux 5 : kernel (ELSA-2007-0595)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Oracle Linux Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165049 (SUSE Security Update for Kernel (SUSE-SA:2007:053)).

Upgrading eliminates this vulnerability. A possible mitigation has been published 2 days after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (35383), Tenable (67537), SecurityFocus (BID 24818†), OSVDB (37117†) and Secunia (SA25955†).
