The issue is related to errors in handling objects in memory by the ChakraCore JavaScript engine. It could allow a remote attacker to execute arbitrary code using a specially crafted web page. The vulnerability can corrupt memory, enabling an attacker to gain the same user rights as the current user. If the current user has administrative rights, the attacker could take control of the affected system, install programs, view, change, or delete data, or create new accounts with full user rights.
