Descriptions

An issue was discovered in certain Apple products. iOS before 10.2 is affected. macOS before 10.12.2 is affected. watchOS before 3.1.3 is affected. The issue involves the "Kernel" component. It allows local users to execute arbitrary code in a privileged context or cause a denial of service (use-after-free) via unspecified vectors.

Se ha descubierto un problema en ciertos productos Apple. iOS en versiones anteriores a 10.2 está afectado. macOS en versiones anteriores a 10.12.2 está afectado. watchOS en versiones anteriores a 3.1.3 está afectado.
