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
In Wireshark 2.2.7, overly deep mp4 chunks may cause stack exhaustion (uncontrolled recursion) in the dissect_mp4_box function in epan/dissectors/file-mp4.c.

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

A stack exhaustion vulnerability exists in Wireshark 2.2.7's MP4 dissector (dissect_mp4_box function in epan/dissectors/file-mp4.c) where overly deep mp4 chunks trigger uncontrolled recursion, leading to stack exhaustion and potential denial of service via a specially crafted MP4 file.

MitigationUpdate Wireshark to a version containing the fix for this vulnerability, or refrain from opening untrusted MP4 files with vulnerable Wireshark versions.

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. Verify Wireshark is installed
    Run 'wireshark --version' or 'tshark --version' on the command line, or locate wireshark.exe in Program Files on Windows systems
    Affected if Wireshark executable is present on the system
  2. Confirm Wireshark version is 2.2.7
    Compare the installed version number to 2.2.7 exactly - this vulnerability affects only this specific version
    Affected if Version equals exactly 2.2.7
  3. Check MP4 dissector availability
    Attempt to open an MP4 file in Wireshark or check the Plugins section in Wireshark's About dialog for the MP4 dissector module
    Affected if MP4 files can be opened and the MP4 dissector is active

You are affected only if you have Wireshark version 2.2.7 and attempt to open a specially crafted MP4 file that triggers uncontrolled recursion in the dissect_mp4_box function.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

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.
