The issue is related to insufficient handling of objects in memory by the JavaScript ChakraCore engine in Microsoft Edge. This could allow a remote attacker to corrupt memory and execute arbitrary code using a specially crafted web page. Successful exploitation could grant the attacker the same user rights as the current user, potentially leading to control of the affected system if the user has administrative rights. This could enable the attacker to install programs, view, change, or delete data, or create new accounts with full user rights.
