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
An issue was discovered in certain Apple products. macOS before 10.12.5 is affected. The issue involves the "Sandbox" component. It allows attackers to conduct sandbox-escape attacks or cause a denial of service (memory corruption) via a crafted app.

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

This is a sandbox escape vulnerability in macOS prior to version 10.12.5 affecting the Sandbox component. A specially crafted application can exploit this flaw to either break out of the sandbox security restriction (allowing it to access resources outside its permitted scope) or trigger memory corruption resulting in denial of service.

MitigationUpgrade macOS to version 10.12.5 or later, which contains the patch for the Sandbox component 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 installed macOS version
    Run 'sw_vers -productVersion' in Terminal or go to Apple menu > About This Mac
    Affected if The version returned is 10.12.4 or earlier (e.g., 10.12.3, 10.12.2, etc.)
  2. Verify build number if version is ambiguous
    Run 'sw_vers -buildVersion' in Terminal to get the exact build
    Affected if The build corresponds to a pre-10.12.5 release (16F2073 or earlier for 10.12.4, or similar for earlier versions)
  3. Confirm Sandbox is in use
    Check if any sandboxed applications are running using 'ps -ax | grep -i sandbox' or inspect app entitlements
    Affected if Sandbox is active on the system (the vulnerability applies to the Sandbox component itself, which is a core macOS security feature)

You are affected if your macOS version is 10.12.4 or earlier, since the vulnerable Sandbox component exists in all such installations.
