Wireshark up to 2.4.4 IPMI Dissector packet-ipmi-picmg.c Crafted Packet injection

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, which was classified as problematic, was found in Wireshark (Packet Analyzer Software). Affected is an unknown functionality of the file epan/dissectors/packet-ipmi-picmg.c of the component IPMI Dissector. The manipulation as part of a Crafted Packet leads to a injection vulnerability. CWE is classifying the issue as CWE-74. The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. This is going to have an impact on availability. CVE summarizes:

In Wireshark 2.2.0 to 2.2.12 and 2.4.0 to 2.4.4, the IPMI dissector could crash. This was addressed in epan/dissectors/packet-ipmi-picmg.c by adding support for crafted packets that lack an IPMI header.
