Descriptions
An integer overflow was addressed through improved input validation. This issue is fixed in macOS Catalina 10.15.5. An application may be able to execute arbitrary code with kernel privileges.
Se abordó un desbordamiento de enteros por medio de una comprobación de entrada mejorada. Este problema es corregido en macOS Catalina versión 10.15.5. Una aplicación puede ser capaz de ejecutar código arbitrario con privilegios de kernel
This vulnerability allows local attackers to escalate privileges on affected 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 SkyLight module. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of WindowServer.
