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 descubrió 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 involucra al 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 diseñado.

This vulnerability allows remote attackers to disclose sensitive information 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 WebGLRenderingContextBase objects. The issue results from the lack of proper validation of user-supplied data, which can result in a read outside of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
