CVE-2016-7610 Apple CVE debrief

CVE-2016-7610 is a high-severity Apple WebKit memory-corruption issue that can be triggered by a crafted website. The record says it can lead to arbitrary code execution or a denial of service (application crash), and NVD rates it 8.8/High. Because the attack vector is network-based and requires user interaction, systems that browse untrusted web content are the main concern.

Who should care

Apple endpoint administrators, mobile fleet managers, and security teams responsible for iOS, Safari, iCloud, or iTunes deployments should prioritize this. It is especially relevant for users who routinely visit external websites or use browsers and related Apple client software on managed devices.

Technical summary

The NVD record classifies the flaw as CWE-119 and gives a CVSS v3.0 vector of AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. The supplied description ties the issue to WebKit and says a crafted website can cause memory corruption, leading to arbitrary code execution or an application crash. The corpus identifies affected Apple products through both the narrative description and CPE criteria for iOS, Safari, iCloud, and iTunes.

Defensive priority

High. This is an internet-reachable WebKit issue with user interaction required, but it can affect widely used Apple client software and carries full confidentiality, integrity, and availability impact in the CVSS vector.

Recommended defensive actions

  • Apply the Apple security updates referenced by the vendor advisories in the CVE record.
  • Upgrade affected systems to versions later than the affected ranges in the CVE description: iOS 10.2 or later, Safari 10.0.2 or later, iCloud 6.1 or later, and iTunes 12.5.4 or later.
  • Inventory Apple devices and client software to identify any systems still within the affected version ranges listed in the record.
  • Prioritize remediation on endpoints that regularly browse untrusted websites or are exposed to general web traffic.
  • Use the CVE record and linked vendor advisories to validate that all affected product lines are covered in patch management plans.

Evidence notes

The supplied NVD record shows publishedAt 2017-02-20T08:59:02.447Z and modifiedAt 2026-05-13T00:24:29.033Z. The description states the issue affects iOS before 10.2, Safari before 10.0.2, iCloud before 6.1, and iTunes before 12.5.4, and that a crafted website can cause memory corruption, arbitrary code execution, or a crash. The NVD metadata lists CVSS v3.0 AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H and CWE-119. The source item also includes CPE criteria with affected ranges up to iOS 10.1.1, Safari 10.0.1, iCloud 6.0.1, and iTunes 12.5.3; this debrief preserves that corpus detail without resolving the version cutoff discrepancy.
