Linux Kernel 2.6.32.51 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.

Summaryinfo

A vulnerability has been found in Linux Kernel 2.6.32.51 and classified as problematic. This vulnerability affects unknown code. The manipulation leads to denial of service. This vulnerability is listed as CVE-2011-3188. There is no available exploit.

Detailsinfo

A vulnerability, which was classified as critical, has been found in Linux Kernel 2.6.32.51 (Operating System). This issue affects an unknown part. The manipulation with an unknown input leads to a denial of service vulnerability. Using CWE to declare the problem leads to CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The (1) IPv4 and (2) IPv6 implementations in the Linux kernel before 3.1 use a modified MD4 algorithm to generate sequence numbers and Fragment Identification values, which makes it easier for remote attackers to cause a denial of service (disrupted networking) or hijack network sessions by predicting these values and sending crafted packets.

The issue has been introduced in 12/03/2009. The weakness was presented 05/24/2012 by Dan Kaminsky (Website). The advisory is shared at github.com. The identification of this vulnerability is CVE-2011-3188 since 08/19/2011. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 903 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 69873 (Juniper NSM Linux Kernel TCP Sequence Number Generation Issue (PSN-2012-08-688)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Misc.. The commercial vulnerability scanner Qualys is able to test this issue with plugin 216036 (VMware ESXi and ESX Third Party Libraries Updates (VMSA-2012-0013)).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at Tenable (69873), SecurityFocus (BID 49289†) and Vulnerability Center (SBV-32830†). See VDB-4416, VDB-5260, VDB-56641 and VDB-60957 for similar entries. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
