Descriptions

An issue was discovered in certain Apple products. iOS before 10.3 is affected. Safari before 10.1 is affected. tvOS before 10.2 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 ciertos productos Apple. iOS en versiones anteriores a 10.3 está afectado. Safari en versiones anteriores a 10.1 está afectado. tvOS en versiones anteriores a 10.2 está afectado. El problema involucra al componente "WebKit". Esto permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (corrupción de memoria y caída de aplicación) a través de un sitio web manipulado.

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 Node 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.

WebKit suffers from a use-after-free vulnerability in HTMLInputElement.
