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 Safari before 6.0, 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-2012-07-25-1.

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 rendering engine, as used in Apple Safari before version 6.0, allowing remote attackers to execute arbitrary code or cause denial of service via malicious crafted web pages.

MitigationUpdate Safari to version 6.0 or later to obtain the patched WebKit component; alternatively, restrict or disable Safari browsing until the update can be deployed.

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. Confirm Safari is installed
    On macOS, check /Applications folder for Safari.app or run 'ls /Applications | grep -i safari'. On Windows, check Program Files folders or run 'Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select DisplayName' to list installed applications.
    Affected if Safari application is found on the system
  2. Determine installed Safari version
    On macOS, right-click Safari.app > Get Info or run 'defaults read /Applications/Safari.app/Contents/Info CFBundleShortVersionString'. On Windows, check Help > About Safari or right-click Safari.exe > Properties > Details.
    Affected if A version number is retrieved from the installation
  3. Compare version against affected ranges
    Compare your installed Safari version to the affected list: versions <= 5.1.7, or any of these: 1.0, 1.0.0, 1.0.0b1, 1.0.0b2, 1.0.1, 1.0.2, 1.0.3, 1.0b1, 1.1, 1.1.0, 1.1.1. Version 6.0 and later are NOT affected.
    Affected if Installed version matches any version in the affected list or is lower than 6.0 (for versions between 1.1.1 and 5.1.7, treat as affected as they pre-date 6.0)

If Safari is installed and its version is 6.0 or later, the environment is NOT affected by this CVE; otherwise, the WebKit vulnerability is present.

dbcve · scoped
Upgrade available Upgrade to a release after 5.1.7
Interim mitigation

Update Safari to version 6.0 or later to obtain the patched WebKit component; alternatively, restrict or disable Safari browsing until the update can be deployed.

Recommended fix High confidence

Safari 6.0 or later (bundled with OS X Mountain Lion 10.8)

  1. Open Safari and click Safari > About Safari to check the current version
  2. If running Safari 5.1.7 or earlier, upgrade by installing OS X Mountain Lion (10.8) or later from the Mac App Store, which includes Safari 6.0 or higher
  3. Alternatively, use System Preferences > Software Update to install the latest Safari version available for your OS
  4. After upgrading, verify the fix by checking Safari > About Safari shows version 6.0 or later
Caveat Requires OS X Mountain Lion (10.8) or later; older Mac systems running OS X 10.7 or earlier cannot upgrade to Safari 6.0 and may need to stay on older Safari versions or consider system upgrade
