CVE-2016-7660 Apple CVE debrief

Who should care

Administrators and defenders responsible for Apple endpoints, especially fleets with older iOS, macOS, or watchOS versions. It is also relevant for organizations that allow untrusted local code execution, shared-user environments, or developer/test devices where local privilege escalation would materially increase impact.

Technical summary

The vulnerability is a local attack with high impact once an attacker already has local execution or some local foothold. The NVD vector lists low attack complexity, low privileges, no user interaction, and high impact to confidentiality, integrity, and availability. The affected component is syslog, and the published material ties the issue to Mach port name references. The supplied corpus does not include a full root-cause description or exploit mechanics, so defenders should treat this as a privilege boundary bypass in Apple’s local logging/system path rather than assume a broader remote exposure.

Defensive priority

High for any environment with vulnerable Apple endpoints exposed to untrusted local code or shared access; medium otherwise after patching is verified. Because the issue enables privilege escalation, a successful local compromise can be a stepping stone to broader device or data compromise.

Recommended defensive actions

• Verify remediation against the affected Apple versions listed in the supplied record and upgrade to the fixed releases referenced by Apple’s advisories.
• Prioritize patching on systems that permit local code execution from multiple users, developer workstations, lab devices, or kiosks.
• Review access controls that reduce opportunities for untrusted local execution while patching is pending.
• Confirm endpoint compliance using asset inventory and OS version checks rather than relying on application-level status alone.
• Monitor Apple security advisory references for the exact fixed build numbers applicable to your platform fleet.

Evidence notes

Evidence in the supplied corpus: Apple vendor advisories are referenced for iOS, macOS, and watchOS; the CVE description identifies the syslog component and Mach port name references; NVD records the vulnerability as local, low-privilege, no-user-interaction with high CIA impact. Note that the supplied description says iOS before 10.2, macOS before 10.12.2, and watchOS before 3.1.3, while the NVD CPE criteria in the same corpus enumerate iOS through 10.1.1, macOS through 10.12.1, and watchOS through 2.2.2.
