Linux Kernel 2.6.20.1 ipv6_getsockopt_sticky denial of service

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 was found in Linux Kernel 2.6.20.1 (Operating System). It has been classified as critical. This affects the function ipv6_getsockopt_sticky. 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 confidentiality, integrity, and availability. The summary by CVE is:

The ipv6_getsockopt_sticky function in net/ipv6/ipv6_sockglue.c in the Linux kernel before 2.6.20.2 allows local users to read arbitrary kernel memory via certain getsockopt calls that trigger a NULL dereference.

The bug was discovered 03/09/2007. The weakness was published 03/12/2007 (Website). The advisory is shared at kb.cert.org. This vulnerability is uniquely identified as CVE-2007-1000 since 02/16/2007. The exploitability is told to be easy. An attack has to be approached locally. No form of authentication is needed for exploitation. Technical details and a public exploit are known.

A public exploit has been developed in ANSI C and been published 4 months after the advisory. The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 35 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 27294 (openSUSE 10 Security Update : kernel (kernel-3128)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 115529 (Fedora Core Kernel Update Not Installed).

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