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

  - A denial of service (DoS) vulnerability. An attacker can exploit this issue to cause the affected component to deny
    system or application services. (CVE-2021-26423)

  - An information disclosure vulnerability. An attacker can exploit this to disclose potentially sensitive
    information. (CVE-2021-34485, CVE-2021-34532)

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