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
Buffer overflow in QT Media Foundation in Apple OS X before 10.9.5 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted MIDI file.

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

Buffer overflow in QT Media Foundation in Apple OS X versions prior to 10.9.5 allows remote attackers to execute arbitrary code or cause denial of service via a crafted MIDI file containing malformed data that overflows a buffer during parsing.

MitigationUpgrade to OS X 10.9.5 or later which contains the security fix for this vulnerability.

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 your OS X version
    Click Apple menu > About This Mac. The version number is displayed below the macOS name (e.g., 10.9.4, 10.9.5, etc.).
    Affected if The installed version is 10.7.5, 10.8.5, 10.9, 10.9.1, 10.9.2, 10.9.3, or 10.9.4 (OS X Server 10.7.5 is also affected). Versions 10.9.5 and later are not affected.
  2. Confirm QT Media Foundation is present
    This component is part of the core QuickTime framework in OS X. It is present by default in affected OS X versions. No manual check needed if OS X version is confirmed.
    Affected if QT Media Foundation is included by default in all affected OS X versions listed above.
  3. Identify if MIDI file processing occurs
    Review what applications on the system can open or process MIDI files (e.g., GarageBand, Logic Pro, QuickTime Player, third-party audio software). Check recent file access logs if available.
    Affected if The vulnerability is triggered when parsing a crafted MIDI file. If no applications process MIDI files, the attack surface is reduced, but the system is still vulnerable if running an affected OS X version.

You are affected if your installed OS X version is 10.7.5, 10.8.5, 10.9, 10.9.1, 10.9.2, 10.9.3, or 10.9.4 (or OS X Server 10.7.5) and you have applications that can parse MIDI files.

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.
