Chakra Core vulnerable to privilege escalation due to type confusion
ChakraCore and Microsoft Edge in Windows 10 1709 and Windows Server, version 1709 allows an attacker to gain the same user rights as the current user, due to how the scripting engine handles objects in memory, aka "Scripting Engine Memory Corruption Vulnerability".
