Descriptions
The WebKit Canvas implementation in Apple iOS before 9.3.2, Safari before 9.1.1, and tvOS before 9.2.1 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site.
La implementación WebKit Canvas en Apple iOS en versiones anteriores a 9.3.2, Safari en versiones anteriores a 9.1.1 y tvOS en versiones anteriores a 9.2.1 permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de memoria) a través de 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 GraphicsContext objects. By manipulating a document's elements an attacker can force this object in memory to be reused after it has been freed. An attacker can leverage this vulnerability to execute code under the context of the current process.
A large number of security issues were discovered in the WebKitGTK+ Web and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary code execution.
