Linux Kernel 2.6.16.9 ioctl_standard_iw_point numeric error

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability, which was classified as critical, has been found in Linux Kernel 2.6.16.9 (Operating System). This issue affects the function ioctl_standard_iw_point. The manipulation with an unknown input leads to a numeric error vulnerability. Using CWE to declare the problem leads to CWE-189. Impacted is confidentiality. The summary by CVE is:

The cfg80211_wext_giwessid function in net/wireless/wext-compat.c in the Linux kernel before 2.6.36-rc3-next-20100831 does not properly initialize certain structure members, which allows local users to leverage an off-by-one error in the ioctl_standard_iw_point function in net/wireless/wext-core.c, and obtain potentially sensitive information from kernel heap memory, via vectors involving an SIOCGIWESSID ioctl call that specifies a large buffer size.

The issue has been introduced in 03/20/2006. The weakness was released 09/08/2010 (Website). The advisory is shared at kernel.org. The identification of this vulnerability is CVE-2010-2955. The exploitation is known to be easy. Access to the local network is required for this attack to succeed. No form of authentication is needed for a successful exploitation. Technical details are known, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 1633 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 68175 (Oracle Linux 5 : Unbreakable Enterprise kernel (ELSA-2010-2011)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Oracle Linux Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 155569 (Oracle Linux 5 Unbreakable Enterprise Kernel Security and Bug Fix Update (ELSA-2010-2011)).

Applying the patch 42da2f948d949efd0111309f5827bf0298bcc9a4 is able to eliminate this problem.

The vulnerability is also documented in the databases at Tenable (68175), SecurityFocus (BID 42885†) and Vulnerability Center (SBV-27253†). Entries connected to this vulnerability are available at VDB-4176, VDB-55542, VDB-55538 and VDB-55535. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
