CVE-2016-7648 Apple CVE debrief

Who should care

Organizations and individuals running affected Apple versions should care, especially if they use Safari for general browsing or rely on iOS, iCloud, or iTunes deployments that were not updated past the vulnerable versions. Security teams supporting Apple endpoints should prioritize patch verification because the issue is remotely triggerable through web content and impacts multiple widely used products.

Technical summary

NVD classifies the weakness as CWE-119 (memory corruption) with CVSS 3.0 vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. The source corpus states that a crafted website can lead to arbitrary code execution or a denial-of-service crash in WebKit. The vulnerable ranges in NVD are encoded as iOS through 10.1.1, Safari through 10.0.1, iCloud through 6.0.1, and iTunes through 12.5.3; the human-readable description summarizes these as versions before iOS 10.2, Safari 10.0.2, iCloud 6.1, and iTunes 12.5.4.

Defensive priority

High. This is a remotely reachable browser-engine flaw with code-execution potential and no privileges required, though user interaction is needed. The combination of broad product impact and high CVSS makes timely patch validation important.

Recommended defensive actions

• Update affected Apple products to versions newer than the vulnerable ranges listed in the source corpus.
• Verify iOS devices are beyond 10.1.1 and confirm Safari, iCloud, and iTunes installations are beyond the listed vulnerable versions.
• Review Apple security advisories linked in the source corpus for the product-specific fixed releases and deployment guidance.
• Prioritize patching on internet-facing or high-browsing-risk endpoints first, since exploitation is triggered through crafted web content.
• Use endpoint inventory and compliance checks to confirm no affected Apple versions remain in production or on unmanaged devices.

Evidence notes

All claims here are taken from the supplied corpus and official links. NVD lists the issue as Apple WebKit memory corruption (CWE-119) with CVSS 3.0 AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. The corpus includes Apple vendor advisories and third-party references. The description states affected versions are iOS before 10.2, Safari before 10.0.2, iCloud before 6.1, and iTunes before 12.5.4; the NVD CPE criteria encode the vulnerable ranges as ending at 10.1.1, 10.0.1, 6.0.1, and 12.5.3 respectively.
