Descriptions

An issue was discovered in certain Apple products. macOS before 10.12.2 is affected. The issue involves the "CoreStorage" component. It allows local users to cause a denial of service (NULL pointer dereference) via unspecified vectors.

Se ha descubierto un problema en ciertos productos Apple. macOS en versiones anteriores a 10.12.2 está afectado. El problema involucra al componente "CoreStorage". Esto permite a usuarios locales provocar una denegación de servicio (referencia a puntero NULL) a través de vectores no especificados.

This vulnerability allows local attackers to escalate privileges on vulnerable installations of Apple macOS. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within CoreStorage. The issue lies with the failure to validate user-supplied arguments which can cause a null pointer dereference. An attacker can leverage this vulnerability to escalate privileges and execute code under the context of the kernel.
