An issue was discovered in certain Apple products. iOS before 10.3 is affected. macOS before 10.12.4 is affected. tvOS before 10.2 is affected. watchOS before 3.2 is affected. The issue involves the “Kernel” component. It allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app.

An issue was discovered in certain Apple products. iOS before 10.3 is affected. Safari before 10.1 is affected. tvOS before 10.2 is affected. The issue involves the “WebKit” component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site.

An issue was discovered in certain Apple products. iOS before 10.3 is affected. The issue involves the “SafariViewController” component. It allows attackers to obtain sensitive information by leveraging the SafariViewController’s incorrect synchronization of Safari cache clearing.

An issue was discovered in certain Apple products. macOS before 10.12.4 is affected. The issue involves mishandling of profile uninstall actions in the “MCX Client” component when a profile has multiple payloads. It allows remote attackers to bypass intended access restrictions by leveraging Active Directory certificate trust that should not have remained.

An issue was discovered in certain Apple products. macOS before 10.12.4 is affected. The issue involves the “Printing” component. A format-string vulnerability allows remote attackers to execute arbitrary code via a crafted ipp: or ipps: URL.
