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
WebKit, as used in Apple iOS before 6.1, 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-2013-01-28-1.

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 corruption vulnerability in WebKit allowing remote code execution or denial of service via malicious website. Affects iOS devices before version 6.1. The vulnerability stems from improper memory handling during web page rendering, enabling attackers to corrupt memory and potentially execute arbitrary code.

MitigationUpdate affected iOS devices to version 6.1 or later. For applications embedding WebKit, update to a WebKit version that includes the patch for this CVE.

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 the iOS version on the device
    Navigate to Settings > General > About > Version on the iOS device
    Affected if The version displayed is 6.0, 6.0.1, or 6.0.2
  2. Confirm the iOS build number matches affected releases
    In Settings > General > About, note the Build number. For 6.0.2, the build is typically 10A702. Compare against Apple's release notes for iOS 6.1 to confirm the device can be updated to 6.1 or later.
    Affected if The device is running iOS 6.0.2 with build 10A702 and cannot be updated to iOS 6.1 or higher
  3. Identify if applications using embedded WebKit are in use
    For third-party iOS applications that embed the WebKit rendering engine, check the application's documentation or binary for the WebKit version it includes
    Affected if The application embeds a version of WebKit prior to the patch date for CVE-2013-0954 (February 2013)

The device or application is affected if it runs iOS version 6.0, 6.0.1, or 6.0.2 and cannot be updated to iOS 6.1 or later, or if it embeds an unpatched version of WebKit.
