Detailsinfo

A vulnerability was found in Linux Kernel up to 2.6.21 (Operating System). It has been rated as problematic. Affected by this issue is an unknown code block. The manipulation with an unknown input leads to a resource management vulnerability. Using CWE to declare the problem leads to CWE-399. Impacted is availability. CVE summarizes:

The disconnect method in the Philips USB Webcam (pwc) driver in Linux kernel 2.6.x before 2.6.22.6 "relies on user space to close the device," which allows user-assisted local attackers to cause a denial of service (USB subsystem hang and CPU consumption in khubd) by not closing the device after the disconnect is invoked. NOTE: this rarely crosses privilege boundaries, unless the attacker can convince the victim to unplug the affected device.

The bug was discovered 09/02/2007. The weakness was published 09/26/2007 by Oliver with SuSE.de (Website). The advisory is shared for download at marc.info. This vulnerability is handled as CVE-2007-5093 since 09/26/2007. The exploitation is known to be difficult. The attack needs to be approached locally. 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 24 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 67762 (Oracle Linux 4 : kernel (ELSA-2008-0972)), 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 117311 (CentOS Security Update for Kernel (CESA-2008:0275)).

Upgrading to version 2.6.22 eliminates this vulnerability. A possible mitigation has been published 2 years after the disclosure of the vulnerability.
