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-2016-0191 and CVE-2016-0193.
El motor Chakra JavaScript en Microsoft Edge permite a atacantes remotos ejecutar código arbitrario or provocar una denegación de servicio (corrupción de memoria) a través de un sitio web manipulado, también conocido como "Scripting Engine Memory Corruption Vulnerability", una vulnerabilidad diferente a CVE-2016-0191 y CVE-2016-0193.
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 Array.unshift method. By performing certain operations in script, an attacker can cause JavaScript to read uninitialized data from a memory location on the stack. An attacker can leverage this to execute code under the context of the current process.
