How to fix?
Microsoft.ChakraCore to version 1.11.9 or higher.
Affected versions of this package are vulnerable to Memory Corruption. It could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
