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 iTunes before 11.0.3, allows man-in-the-middle attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via vectors related to iTunes Store browsing, a different vulnerability than other WebKit CVEs listed in APPLE-SA-2013-05-16-1.

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, the rendering engine used by Apple iTunes, allows remote attackers to achieve arbitrary code execution or cause application crashes via a man-in-the-middle attack while users browse the iTunes Store. The vulnerability stems from improper handling of web content during Store browsing sessions.

MitigationUpdate Apple iTunes to version 11.0.3 or later to incorporate the patched WebKit component. For managed environments, deploy the update via standard patch management infrastructure and verify successful installation across all affected clients.

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. Verify iTunes is installed
    On Windows, check Program Files\iTunes or the Windows Registry (HKLM\SOFTWARE\Apple Inc.\iTunes). On Mac, check /Applications for iTunes.app.
    Affected if iTunes is present on the system
  2. Determine installed iTunes version
    On Windows, open iTunes and go to Help > About iTunes, or check the version in the Windows Registry at HKLM\SOFTWARE\Apple Computer, Inc.\iTunes\Version. On Mac, open iTunes and check iTunes > About iTunes.
    Affected if The version displayed is 11.0.2 or lower, or matches any of these specific versions: 4.0.0, 4.0.1, 4.1.0, 4.2.0, 4.5, 4.5.0, 4.6, 4.6.0, 4.7, 4.7.0, 4.7.1
  3. Confirm iTunes Store browsing is accessible
    Launch iTunes and verify the iTunes Store section is available and was previously used. The vulnerability is triggered during Store browsing sessions.
    Affected if The iTunes Store feature is accessible and was used on this installation

A system is affected if iTunes is installed with version 11.0.2 or lower, or with any of the specific 4.x versions listed, and the iTunes Store feature has been accessed.

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.

dbcve · scoped
Upgrade available Upgrade to a release after 11.0.2
Interim mitigation

Update Apple iTunes to version 11.0.3 or later to incorporate the patched WebKit component. For managed environments, deploy the update via standard patch management infrastructure and verify successful installation across all affected clients.

Recommended fix High confidence

iTunes 11.0.3 or later; iOS 7 or later for iPhone/iPad devices

  1. 1. Open Apple iTunes on your computer
  2. 2. If automatic updates are enabled, iTunes will prompt you to update. If not, go to Help > Check for Updates
  3. 3. Download and install iTunes 11.0.3 or later (the latest available version is recommended)
  4. 4. For iPhone OS (iOS) devices, update via Settings > General > Software Update on the device itself to a version newer than 6.1.4 (iOS 7 or later is recommended for security support)
Caveat iTunes 11.0.3 requires Windows 7 or later or Mac OS X 10.6.8 or later; older iOS devices may not support newer iOS versions
