Permite a los atacantes remotos ejecutar un código arbitrario o causar una denegación de servicio (corrupción de memoria y bloqueo de aplicación) por medio de un sitio web creado.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Safari. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the handling of RenderLayer objects. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code under the context of the current process.
