The Chakra JavaScript scripting 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-2016-7200, CVE-2016-7201, CVE-2016-7202, CVE-2016-7208, CVE-2016-7240, CVE-2016-7242, and CVE-2016-7243.
El motor de secuencias de comandos Chakra 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, vulnerabilidad también conocida como "Scripting Engine Memory Corruption Vulnerability", una vulnerabilidad diferente a CVE-2016-7200, CVE-2016-7201, CVE-2016-7202, CVE-2016-7208, CVE-2016-7240, CVE-2016-7242 y CVE-2016-7243.
There is a heap overflow in Array.splice in Chakra. When an array is spliced, and overflow check is performed, but ArraySpeciesCreate, which can execute code and alter the array is called after this. This can allow an Array with boundaries that cause integer overflows to be spliced, leading to heap overflows in several situations.
