It is, therefore, affected by multiple vulnerabilities including the following:

  - A denial of service (DoS) vulnerability exists in Microsoft Visual Studio 2019. An unauthenticated, 
    remote attacker can exploit this issue to cause the application to stop responding. (CVE-2021-26423)

  - An information disclosure vulnerability exists in Microsoft Visual Studio 2019. An authenticated, 
    local attacker can exploit this to disclose potentially sensitive information. (CVE-2021-34532)
