CVE-2014-4414
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 · uneditedWebKit, as used in Apple iOS before 8 and Apple TV before 7, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site, a different vulnerability than other WebKit CVEs listed in APPLE-SA-2014-09-17-1 and APPLE-SA-2014-09-17-2.
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 confidenceA memory corruption vulnerability in WebKit, as shipped in Apple iOS before version 8 and Apple TV before version 7, allows remote attackers to achieve arbitrary code execution or cause denial of service via a crafted malicious website. The vulnerability stems from improper memory handling during web content processing.

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 iOS version on iPhone or iPadGo to Settings > General > About > Version to see the installed iOS version numberAffected if The version is 7.0, 7.0.1, 7.0.2, 7.0.3, 7.0.4, 7.0.5, 7.0.6, 7.1, 7.1.1, or 7.1.2 (any version 7.x up to 7.1.2)
-
Check Apple TV versionGo to Settings > General > About > Version on Apple TV to see the installed tvOS version numberAffected if The version is 6.0, 6.0.1, 6.0.2, 6.1, 6.1.1, 6.1.2, or 6.2 (any version 6.x up to 6.2)
-
Check Mac OS X versionClick Apple menu > About This Mac to see the OS X version numberAffected if The version is 10.9.4 or earlier, including any 10.9.x release up to 10.9.4
-
Determine if WebKit-based browser is in useIdentify if Safari or any third-party app using WebKit (such as certain mail clients or messaging apps) is actively used on the deviceAffected if The vulnerable WebKit component is exposed when Safari or any WebKit-based application processes untrusted web content
The user is affected if the device runs iOS 7.x up to 7.1.2, tvOS 6.x up to 6.2, or Mac OS X 10.9.4 or earlier, AND the device uses Safari or any application that processes web content via the WebKit 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 iOS devices to version 8 or later and Apple TV devices to version 7 or later to obtain the patched WebKit component. For third-party applications using WebKit, update to a WebKit revision containing the security fix.
