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 versiones anteriores a 10.3.2 está afectado. Safari versiones anteriores a 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 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 B3 optimizations. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code under the context of the current process.
WebKit JSC suffers from a JIT optimization check failure in IntegerCheckCombiningPhase::handleBlock.
