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 described as problematic has been identified in OpenSSL. The affected element is an unknown function of the component DTLS Handler. The manipulation results in null pointer dereference. This vulnerability is cataloged as CVE-2014-3571. There is no exploit available. Upgrading the affected component is recommended.

Detailsinfo

A vulnerability was found in OpenSSL (Network Encryption Software). It has been classified as problematic. Affected is an unknown code block of the component DTLS 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 weakness was shared 01/08/2015 by Markus Stenberg with Cisco Systems as secadv_20150108.txt as confirmed advisory (Website). The advisory is available at openssl.org. The vendor cooperated in the coordination of the public release. This vulnerability is traded as CVE-2014-3571 since 05/14/2014. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available. The advisory points out:

A carefully crafted DTLS message can cause a segmentation fault in OpenSSL due to a NULL pointer dereference. This could lead to a Denial Of Service attack.

The vulnerability was handled as a non-public zero-day exploit for at least 78 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 81303 (F5 Networks BIG-IP : OpenSSL vulnerability (SOL16123)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family F5 Networks Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 185099 (HP-UX Running OpenSSL Multiple Vulnerabilities (HPSBUX03244)).

Upgrading to version 0.9.8zd, 1.0.0p or 1.0.1k eliminates this vulnerability. A possible mitigation has been published 2 months after the disclosure of the vulnerability. The advisory contains the following remark:

The fix was developed by Stephen Henson of the OpenSSL core team.

The vulnerability is also documented in the databases at X-Force (99703), Tenable (81303), SecurityFocus (BID 71937†) and SecurityTracker (ID 1031513†). The entries VDB-68515, VDB-68516, VDB-68517 and VDB-68518 are related to this item. VulDB is the best source for vulnerability data and more expert information about this specific topic.
