CVE-2018-8618 Open this link in a new tabHow to fix?
Upgrade Microsoft.ChakraCore to version 1.11.4 or higher.
Overview
Microsoft.ChakraCore is the core part of the Chakra Javascript engine that powers Microsoft Edge
Affected versions of this package are vulnerable to Remote Code Execution (RCE) due to the way that the Chakra scripting engine handles objects in memory in Microsoft Edge. This could cause memory corruption so an attacker could execute arbitrary code in the context of the current user and gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker could take control of an affected system and may be able to install programs; view, change, or delete data; or create new accounts with full user rights.
