Descriptions

An issue was discovered in certain Apple products. macOS before 10.12.2 is affected. The issue involves the "IOAcceleratorFamily" 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 "IOAcceleratorFamily". 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 IOCommandQueue. 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.

macOS 10.12.2 is now available and addresses arbitrary code execution, denial of service, and various other vulnerabilities.
