The Chakra JavaScript engine in Microsoft Edge allows 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," a different vulnerability than CVE-2016-3214.
El motor Chakra de JavaScript en Microsoft Edge permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (corrupción de memoria) a través de un sitio web manipulado, también conocida como "Scripting Engine Memory Corruption Vulnerability", una vulnerabilidad diferente a CVE-2016-3214.
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Edge. 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 implementation of the JavaScript map method, as defined on typed arrays. By performing certain operations in script, an attacker can cause JavaScript to write outside the bounds of the array. An attacker can leverage this to execute code under the context of the current process.
