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 issue was addressed with improved memory handling. This issue is fixed in macOS Monterey 12.7.6, macOS Sonoma 14.6, macOS Ventura 13.6.8. Processing a maliciously crafted file may lead to a denial-of-service or potentially disclose memory contents.

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 · moderate confidence

Memory handling vulnerability in macOS that occurs when processing a maliciously crafted file, potentially leading to denial of service or disclosure of memory contents due to improper memory management during file parsing.

MitigationApply the vendor-supplied macOS security updates (Monterey 12.7.6, Ventura 13.6.8, or Sonoma 14.6) and exercise caution when opening files from untrusted sources.

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. Identify macOS version
    Run 'sw_vers -ProductVersion' in Terminal to retrieve the installed macOS version number
    Affected if The version is 12.0 to 12.7.5, 13.0 to 13.6.7, or 14.0 to 14.5 (any version before the fixed releases)
  2. Confirm macOS release name
    Run 'sw_vers -ProductVersionExtra' or check the macOS version against known release names: 12.x is Monterey, 13.x is Ventura, 14.x is Sonoma
    Affected if The system is running Monterey, Ventura, or Sonoma within the vulnerable version ranges
  3. Verify patch status
    Check System Settings > General > Software Update for available security updates, or run 'system_profiler SPSoftwareDataType' to see installed security updates
    Affected if Security Update [CVE-2024-27877] or the vendor-supplied patches (Monterey 12.7.6, Ventura 13.6.8, Sonoma 14.6) are not installed

You are affected if your macOS version is 12.0-12.7.5, 13.0-13.6.7, or 14.0-14.5 and the corresponding security update has not been applied.

Interim mitigation

Apply the vendor-supplied macOS security updates (Monterey 12.7.6, Ventura 13.6.8, or Sonoma 14.6) and exercise caution when opening files from untrusted sources.

Recommended fix High confidence

macOS Monterey 12.7.6, macOS Ventura 13.6.8, or macOS Sonoma 14.6 (depending on current major version)

  1. 1. Determine the current macOS version by clicking the Apple menu > About This Mac
  2. 2. Back up your Mac using Time Machine or another backup solution before applying the update
  3. 3. If running macOS Monterey (12.x), update to macOS 12.7.6: Open System Settings > General > Software Update and install available updates
  4. 4. If running macOS Ventura (13.x), update to macOS 13.6.8: Open System Settings > General > Software Update and install available updates
  5. 5. If running macOS Sonoma (14.x), update to macOS 14.6: Open System Settings > General > Software Update and install available updates
  6. 6. After updating, verify the system is running the fixed version via About This Mac
Caveat Standard macOS point updates typically have minimal breaking changes; backup recommended before updating
