Descriptions

An issue was discovered in certain Apple products. Safari before 10.1 is affected. The issue involves the "WebKit" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site.

Se ha descubierto un problema en algunos productos Apple. Se ha visto afectado Safari en versiones anteriores a la 10,1. El problema afecta al componente "WebKit". Permite que atacantes remotos ejecuten código arbitrario o provoquen una denegación de servicio (corrupción de memoria y cierre inesperado de la aplicación) mediante una página web manipulada.

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 HTMLSlotElement 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.
