Remote Code Execution (RCE)

Microsoft Chakracore is vulnerable to remote code execution RCE. It does not properly handle the JIT bails out when there is an object marked as temporary during an implicit call, allowing objects stored on the stack to be used outside of the function during the DeadStore pass of GlobOpt...

Remote Code Execution (RCE)

Microsoft.ChakraCore is vulnerable to remote code execution RCE attacks. The library interpreter contains a Implicit call bypass in GlobalOpt.cpp, allowing a malicious user to inject and execute arbitrary code...
