Descriptions

The scripting engines in Microsoft Internet Explorer 9 through 11 and Microsoft Edge allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, aka "Scripting Engine Memory Corruption Vulnerability," as demonstrated by the Chakra JavaScript engine, a different vulnerability than CVE-2016-7200, CVE-2016-7201, CVE-2016-7203, CVE-2016-7208, CVE-2016-7240, CVE-2016-7242, and CVE-2016-7243.

Los motores de secuencia en Microsoft Internet Explorer 9 hasta la versión 11 y Microsoft Edge permiten a atacantes remotos ejecutar un código arbitrario o provocar una denegación de servicio (corrupción de memoria) a través de un sitio web manipulado, vulnerabilidad también conocida como "Scripting Engine Memory Corruption Vulnerability", como es demostrado por el motor Chakra JavaScript, una vulnerabilidad distinta a CVE-2016-7200, CVE-2016-7201, CVE-2016-7203, CVE-2016-7208, CVE-2016-7240, CVE-2016-7242 y CVE-2016-7243.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Internet Explorer. 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 processing of the JavaScript method Array.splice. By performing actions in JavaScript an attacker can corrupt the state of a JavaScript array. An attacker can leverage this vulnerability to execute arbitrary code under the context of the current process.
