CVE-2015-3659
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 · uneditedThe SQLite authorizer in the Storage functionality in WebKit in Apple Safari before 6.2.7, 7.x before 7.1.7, and 8.x before 8.0.7, as used in Apple iOS before 8.4 and other products, does not properly restrict access to SQL functions, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted web site.

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 is displayed next to 'Safari'.Affected if Version is 6.2.6 or earlier, or 7.0.x through 7.1.3 inclusive (7.0, 7.0.1, 7.0.2, 7.0.3, 7.0.4, 7.0.5, 7.0.6, 7.1.0, 7.1.1, 7.1.2, 7.1.3)
-
Check iOS version on iPhone/iPadGo to Settings > General > About. The version number is shown next to 'Version'.Affected if Version is 8.3 or earlier (includes all versions up to and including 8.3)
-
Check macOS versionClick Apple menu > About This Mac. The version number is displayed below the macOS name (such as 10.10.3).Affected if macOS version is 10.10.3 or earlier
-
Confirm WebKit Storage usageThis vulnerability affects WebKit's SQLite authorizer used by Storage features (Web SQL Database). The flaw is triggered when a malicious web page uses crafted SQL operations through the Storage API.Affected if The affected Safari/iOS browser is used to visit untrusted web pages that leverage Web SQL Database storage functionality
A user is affected if they run Safari versions 6.2.6 or earlier, 7.0.x through 7.1.3, iOS 8.3 or earlier, or macOS 10.10.3 or earlier, and browse the web with JavaScript/Web SQL Database enabled.

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 Safari to version 6.2.7+, 7.1.7+, or 8.0.7+ and iOS devices to version 8.4 or later to obtain the patched WebKit with proper SQLite authorizer restrictions.
