Descriptions

An issue was discovered in certain Apple products. macOS before 10.12.5 is affected. The issue involves the "Multi-Touch" component. It allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app.

Se descubrió un problema en ciertos productos de Apple. MacOS anterior a versión 10.12.5 está afectado. El problema involucra al componente "Multi-Touch". Permite a los atacantes ejecutar código arbitrario en un contexto privilegiado o causar una denegación de servicio (corrupción de memoria) por medio de una aplicación diseñada.

This vulnerability allows local attackers to disclose sensitive information 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 the handling of the AppleMultitouchDevice kext. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges in the context of the kernel.
