Descriptions

Microsoft Internet Explorer 9 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, aka "Internet Explorer Memory Corruption Vulnerability," a different vulnerability than CVE-2015-6141.

Microsoft Internet Explorer 9 permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de memoria) a través de un sitio web manipulado, también conocida como 'Internet Explorer Memory Corruption Vulnerability', una vulnerabilidad diferente a CVE-2015-6141.

This vulnerability allows remote attackers to execute arbitrary code in applications using the JScript scripting language on vulnerable installations of Microsoft Windows. Microsoft Internet Explorer is an affected application. 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 relates to how JScript handles external objects that also serve as callable objects within script. An "external object" is an object that is provided by the hosting application, as opposed to being provided by the script engine. Through the use of certain script methods, an attacker can cause JScript to use an integer as if it were a pointer to a callable object. An attacker can leverage this to execute arbitrary code in the context of the current process.
