CVE-2016-1827: Apple iOS, macOS, tvOS, watchOS kernel can run malicious code or crash

CVE-2016-1827 · published 10 years ago

Summary

The core part of iOS, macOS, tvOS, and watchOS released before the latest updates can be tricked by a specially crafted app to run any code with system privileges or to make the device stop working. This could let an attacker take control of the device or cause a denial of service. Update the operating systems to the latest versions to protect your devices.

What to do

Update apple iphone_os to version 9.3.2 or later.
Update apple mac_os_x to version 10.11.5 or later.
Update apple tvos to version 9.2.1 or later.
Update apple watchos to version 2.2.1 or later.

Original advisory text

The kernel in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1 allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app, a different vulnerability than CVE-2016-1828, CVE-2016-1829, and CVE-2016-1830.
