CVE-2016-4692
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 · uneditedAn issue was discovered in certain Apple products. iOS before 10.2 is affected. Safari before 10.0.2 is affected. iCloud before 6.1 is affected. iTunes before 12.5.4 is affected. The issue involves the "WebKit" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site.
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.

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 checksWork through these to decide whether this CVE applies to you.
-
Check Safari version on macOSOpen Safari, go to Safari menu > About Safari. The version number displayed must be compared to 10.0.2 (the patched version). Versions 10.0.1 and earlier are vulnerable.Affected if Safari version is 10.0.1 or earlier on macOS
-
Check iOS version on iPhone or iPadGo to Settings > General > About. Look for the Version field. Compare the iOS version to 10.2 (the patched version). Versions 10.1.1 and earlier are vulnerable.Affected if iOS version is 10.1.1 or earlier on the device
-
Check iCloud for Windows versionOpen iCloud (from system tray or Applications). Click on the iCloud icon and look for the version number, or right-click > Properties > Details. Compare to 6.1 (the patched version). Versions 6.0.1 and earlier are vulnerable.Affected if iCloud for Windows version is 6.0.1 or earlier
-
Check iTunes version on Windows or macOSOpen iTunes, go to Help > About iTunes. The version number shown must be compared to 12.5.4 (the patched version). Versions 12.5.3 and earlier are vulnerable.Affected if iTunes version is 12.5.3 or earlier
Any of the following conditions indicate exposure: Safari 10.0.1 or earlier, iOS 10.1.1 or earlier, iCloud 6.0.1 or earlier, or iTunes 12.5.3 or earlier, since the vulnerability is triggerable through malicious web content loaded in the WebKit rendering engine.

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.
From vendor dataUpdate all affected Apple products to patched versions: iOS 10.2+, Safari 10.0.2+, iCloud 6.1+, and iTunes 12.5.4+.
