The security flaw is described as a remote code execution bug that would allow an attack to take full control of an unpatched system, Xinhua news agency reported. An unpatched system is an old system with its security not updated making it vulnerable to viruses and other attacks. The vulnerability could be exploited if malicious files are used on the target computer during the scanning of a computer system with real-time protection turned on. Microsoft is now working with the British agency to have this patched by updating its malware protection engine with the latest version that is capable of removing the bug, the report said.
