How to fix?
Microsoft.ChakraCore to version 1.7.4 or higher.
Affected versions of this package are vulnerable to Remote Code Execution (RCE). A security feature bypass vulnerability exists in Microsoft Edge as a result of how memory is accessed in code compiled by the Edge
Just-In-Time (JIT) compiler that allows Control Flow Guard (CFG) to be bypassed. By itself, this CFG bypass vulnerability does not allow arbitrary code execution. However, an attacker could use the CFG bypass vulnerability in conjunction with another vulnerability, such as a remote code execution vulnerability, to run arbitrary code on a target system.
