Descriptions

An issue was discovered in certain Apple products. macOS before 10.12.2 is affected. The issue involves the "IOSurface" component. It allows local users to obtain sensitive kernel memory-layout information 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 "IOSurface". Esto permite a usuarios locales obtener información sensible del diseño de memoria del kernel a través de vectores no especificados.

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 IOSurface. The process does not properly validate user-supplied data which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges under the context of the kernel.
