Descriptions

In iOS before 11.4 and macOS High Sierra before 10.13.5, a memory corruption issue exists and was addressed with improved memory handling.

En iOS en versiones anteriores a la 11.4 y macOS High Sierra en versiones anteriores a la 10.13.5, existe un problema de corrupción de memoria y se abordó con la mejora de la gestión de memoria.

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 the handling of Mach messages to the Dock. The issue results from the lack of proper validation of the client prior to spawning a process. An attacker can leverage this vulnerability to execute code within the context of the current user.
