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.

A vulnerability, which was classified as problematic, was found in Openswan up to 2.6.35. This affects the function handling of the component Error Handler. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. The summary by CVE is:

Openswan 2.6.29 through 2.6.35 allows remote attackers to cause a denial of service (NULL pointer dereference and pluto IKE daemon crash) via an ISAKMP message with an invalid KEY_LENGTH attribute, which is not properly handled by the error handling function.

The weakness was disclosed 11/17/2011 by Paul (Website). The advisory is shared at openswan.org. This vulnerability is uniquely identified as CVE-2011-3380. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 68365 (Oracle Linux 6 : openswan (ELSA-2011-1356)), 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 155968 (Oracle Enterprise Linux Update for Openswan (ELSA-2011-1356)).

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