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 · high confidence

A memory corruption vulnerability in WebKit allows remote attackers to execute arbitrary code or cause a denial of service via a crafted website. The vulnerability affects Apple iOS versions prior to 6.1 and stems from improper memory handling during web page rendering.

MitigationUpdate affected iOS devices to version 6.1 or later to receive the patched WebKit component. For applications embedding WebKit, rebuild against the updated WebKit library.

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 installed 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 (any version prior to 6.1)
  2. Identify third-party applications that embed WebKit
    Review installed applications for those known to use embedded WebKit components; for developers, inspect app binaries for WebKit framework linkage
    Affected if Any third-party app using WebKit is installed on a vulnerable iOS version (6.0-6.0.2)
  3. For developers: verify WebKit framework version in built applications
    If you build applications that embed WebKit, check the WebKit library version linked against your application binary
    Affected if The application was built against WebKit versions present in iOS 6.0 through 6.0.2

If the device runs iOS 6.0, 6.0.1, or 6.0.2 and uses any WebKit-based application or browses the web with Safari, the environment is affected by this CVE.

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 data
Upgrade available Upgrade to a release after 6.0.2
Interim mitigation

Update affected iOS devices to version 6.1 or later to receive the patched WebKit component. For applications embedding WebKit, rebuild against the updated WebKit library.
