Descriptions

An issue was discovered in certain Apple products. iOS before 10.3.2 is affected. Safari before 10.1.1 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 detectó un problema en ciertos productos de Apple. iOS anterior a versión 10.3.2 está afectado. Safari anterior a versión 10.1.1 está afectado. El problema implica el componente "WebKit". Permite a los atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de memoria y bloqueo de aplicación) por medio de un sitio web especialmente diseñado.

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 RenderElement 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.
