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 12.3, 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-2015-09-16-3.

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 iTunes before version 12.3. Exploitable via man-in-the-middle attacks when users browse the iTunes Store, potentially allowing arbitrary code execution or causing application crash via memory corruption.

MitigationUpdate iTunes to version 12.3 or later to patch the vulnerability. Avoid browsing the iTunes Store on untrusted networks to reduce MITM attack exposure.

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 Safari version
    On Mac: click Safari > About Safari. On Windows: click Help > About Safari. Compare the version number to 8.0.8 or earlier.
    Affected if Safari version is 8.0.8 or earlier on OS X or Windows.
  2. Check iTunes version
    Open iTunes and click Help > About iTunes. Compare the version number to 12.2 or earlier.
    Affected if iTunes version is 12.2 or earlier.
  3. Determine if iTunes Store browsing is enabled
    Open iTunes and look for the iTunes Store icon or menu item. Check if you can access the iTunes Store (sign in and browse content).
    Affected if iTunes Store is accessible and functional on the installed iTunes version.
  4. Verify WebKit component in iTunes
    iTunes uses WebKit to render the iTunes Store interface. There is no direct user-facing setting to disable this component.
    Affected if iTunes is installed and the iTunes Store feature is functional, meaning the WebKit rendering engine is in use.

You are affected if Safari 8.0.8 or earlier is installed, or if iTunes 12.2 or earlier is installed and the iTunes Store feature is accessible and functional on that version.
