Linux Kernel 2.6.16.9 do_tcp_setsockopt 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 has been found in Linux Kernel 2.6.16.9 (Operating System) and classified as problematic. Affected by this vulnerability is the function do_tcp_setsockopt. The manipulation with an unknown input leads to a numeric error vulnerability. The CWE definition for the vulnerability is CWE-189. As an impact it is known to affect availability. The summary by CVE is:

The do_tcp_setsockopt function in net/ipv4/tcp.c in the Linux kernel before 2.6.37-rc2 does not properly restrict TCP_MAXSEG (aka MSS) values, which allows local users to cause a denial of service (OOPS) via a setsockopt call that specifies a small value, leading to a divide-by-zero error or incorrect use of a signed integer.

The issue has been introduced in 03/20/2006. The weakness was published 11/22/2010 by prdelka as confirmed git commit (GIT Repository). The advisory is shared at git.kernel.org. This vulnerability is known as CVE-2010-4165. The exploitation appears to be easy. An attack has to be approached locally. The exploitation doesn't need any form of authentication. Technical details and also a public exploit are known.

A public exploit has been developed by prdelka in ANSI C and been published 4 months after the advisory. It is possible to download the exploit at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1699 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 68414 (Oracle Linux 5 / 6 : Unbreakable Enterprise kernel (ELSA-2011-2010)), 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 165548 (SUSE Enterprise Linux Security Update Linux Kernel (SUSE-SA:2011:004)).

Applying a patch is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (63220), Exploit-DB (16263), Tenable (68414), SecurityFocus (BID 44830†) and OSVDB (69241†). Similar entries are available at VDB-55570, VDB-55526, VDB-56001 and VDB-55935. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
