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 5.1 and iTunes before 10.6, 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-2012-03-07-1 and APPLE-SA-2012-03-07-2.

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 · high confidence

Memory corruption vulnerability in WebKit's rendering engine allows remote attackers to execute arbitrary code or cause a denial of service via a crafted website. The vulnerability stems from improper memory handling when processing malicious web content.

MitigationUpdate affected devices to iOS 5.1 or later and iTunes 10.6 or later to obtain the patched WebKit version. Avoid browsing untrusted websites until patches are applied.

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 iOS version on iPhone or iPad
    Go to Settings > General > About > Version on the iOS device
    Affected if Version number is less than 5.1
  2. Check iTunes version on Windows or Mac
    Open iTunes and go to Help > About iTunes (or iTunes > About iTunes on Mac)
    Affected if Version number is less than 10.6
  3. Identify WebKit-based browser usage
    Note that Safari on iOS and iTunes both use WebKit to render web content; the vulnerability is triggered when these applications process malicious web pages
    Affected if The device runs vulnerable iOS or the system runs vulnerable iTunes AND the user browses websites

The environment is affected if an iOS device runs a version prior to 5.1 or iTunes runs a version prior to 10.6, and the WebKit-based browser (Safari in iOS or the iTunes Store) is used to visit untrusted web content.

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.

Upgrade available Upgrade to 5.1 / 10.6 or later
Fixed in 5.110.6
Interim mitigation

Update affected devices to iOS 5.1 or later and iTunes 10.6 or later to obtain the patched WebKit version. Avoid browsing untrusted websites until patches are applied.

Recommended fix High confidence

iOS 5.1 and iTunes 10.6

  1. For iOS devices: Upgrade to iOS 5.1 or later through Settings > General > Software Update
  2. For desktop systems with iTunes: Upgrade to iTunes 10.6 or later by downloading from apple.com or using the Apple Software Update feature
  3. Alternatively, apply the Apple security updates released in March 2012 (APPLE-SA-2012-03-07-1 and APPLE-SA-2012-03-07-2)
  4. Ensure WebKit-based browsers on affected devices are also updated to their latest versions
Caveat Standard upgrade risks apply - backup device data before performing iOS/iTunes upgrades; some legacy features may be deprecated in newer versions
