Security experts and security companies have claimed that this vulnerability is one of the most critical security flaws that have been detected and fixed by Microsoft this month. This critical flaw (CVE-2021-31166) is akin to corruption of information in the memory of the HTTP protocol stack (http!UlpParseContentCoding) that is already included in all the recent versions of Windows. Microsoft has strongly recommended all its users to install all the security updates published on an immediate basis. This security flaw is quite similar to another Microsoft vulnerability that was detected in the HTTP network stack in 2015.”]
