Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The ipmi_fmt_udpport function in epan/dissectors/packet-ipmi.c in the IPMI dissector in Wireshark 2.0.x before 2.0.1 improperly attempts to access a packet scope, which allows remote attackers to cause a denial of service (assertion failure and application exit) via a crafted packet.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Wireshark's IPMI dissector contains a vulnerability in the ipmi_fmt_udpport function where it improperly attempts to access a packet scope. When processing a specially crafted packet, this improper access triggers an assertion failure, causing Wireshark to terminate unexpectedly. The vulnerability is exploitable remotely via malicious pcap files or captured network traffic containing crafted IPMI packets.

MitigationUpgrade Wireshark to version 2.0.1 or later. Until patched, avoid opening untrusted pcap files or monitoring untrusted network traffic with the IPMI dissector enabled.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check Wireshark version
    Run 'wireshark --version' or 'tshark --version' from command line, or open Wireshark and go to Help > About Wireshark to view the version
    Affected if Version is exactly 2.0.0 (other versions are not affected by this CVE)
  2. Verify IPMI dissector is enabled
    In Wireshark, go to Analyze > Enabled Protocols, then search for 'IPMI' and confirm the checkbox is checked; or check the dissector list in the profile
    Affected if IPMI protocol is enabled (if disabled, the vulnerable code path is not exercised)
  3. Identify exposure to untrusted pcap files or traffic
    Review recent pcap files opened or network interfaces monitored, particularly if handling traffic from untrusted sources containing IPMI protocol packets
    Affected if You have opened pcap files or captured network traffic containing IPMI packets from untrusted or unknown sources

You are affected only if you are running Wireshark version 2.0.0, have the IPMI dissector enabled, and have processed a specially crafted malicious pcap file or network packet containing malformed IPMI data.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade Wireshark to version 2.0.1 or later. Until patched, avoid opening untrusted pcap files or monitoring untrusted network traffic with the IPMI dissector enabled.
