Wireshark up to 1.8.1 STUN Dissector packet-stun.c input validation

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 Wireshark (Packet Analyzer Software). It has been classified as problematic. This affects some unknown processing of the file epan/dissectors/packet-stun.c of the component STUN Dissector. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on availability. The summary by CVE is:

The dissect_stun_message function in epan/dissectors/packet-stun.c in the STUN dissector in Wireshark 1.4.x before 1.4.15, 1.6.x before 1.6.10, and 1.8.x before 1.8.2 does not properly interact with key-destruction behavior in a certain tree library, which allows remote attackers to cause a denial of service (application crash) via a malformed packet.

The weakness was released 08/15/2012 by Laurent Butti as wnpa-sec-2012-21 as confirmed bulletin (Website) via wireshark.org. It is possible to read the advisory at wireshark.org. The public release was coordinated with the project team. This vulnerability is uniquely identified as CVE-2012-4292 since 08/14/2012. The exploitability is told to be easy. Access to the local network is required for this attack to succeed. No form of authentication is needed for exploitation. Technical details of the vulnerability are known, but there is no available exploit.
