Who should care

Organizations that manage Apple endpoints, especially users of Safari on macOS or iOS, and fleets that include iPhone/iPad devices, iTunes clients, or iCloud for Windows. Security teams should also care because the flaw is remotely triggerable through web content and carries high impact.

Technical summary

The weakness is classified as CWE-119 (memory corruption). The vulnerability is in WebKit and is reachable through a crafted website, making network delivery with user interaction the primary exposure path. The NVD vector is CVSS 3.0 AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, consistent with a browser-based attack that can lead to code execution or crashes. The corpus also includes version-range data for vulnerable Apple releases and vendor advisories for remediation.

Defensive priority

High. This is a remotely reachable browser engine flaw with potential code execution impact, so patching should be prioritized for internet-facing and actively used Apple devices and clients.

Recommended defensive actions

  • Update affected Apple products to vendor-fixed releases referenced by the official Apple advisories.
  • Confirm exposure for iOS, Safari, iCloud, and iTunes versions listed in the corpus as vulnerable.
  • Prioritize remediation on devices that browse the web regularly or are used for high-trust activities.
  • Review crash reports and application logs for unexplained Safari/WebKit failures around the affected period.
  • Use managed-device compliance checks to ensure Apple patches are installed and current.
  • Treat any untrusted website content as a potential trigger path until all affected versions are removed.

Evidence notes

The corpus states: iOS before 10.2, Safari before 10.0.2, iCloud before 6.1, and iTunes before 12.5.4 are affected. The NVD CPE ranges in the supplied source item list slightly different maximum affected versions: iphone_os up to 10.1.1, Safari up to 10.0.1, iTunes up to 12.5.3, and iCloud up to 6.0.1.
