"The Microsoft Visual Studio Products are missing a security update. They are, therefore, affected by multiple
vulnerabilities:

  - A denial of service (DoS) vulnerability exists in the OpenSSL component of Visual Studio. An 
    unauthenticated, remote attacker can exploit this issue to cause the application to stop responding. 
    (CVE-2020-1971)

  - Multiple A privilege escalation vulnerabilities exist in Visual Studio. An unauthenticated, local 
    attacker can exploit thees to gain privileged access to the system. (CVE-2021-42277, CVE-2021-42319) 

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version 
number.");
