The Microsoft Visual Studio Products are missing a security update. They are, therefore, affected by multiple vulnerabilities:
Multiple denial of service (DoS) vulnerabilities exist in Visual Studio. An unauthenticated, remote attacker can exploit these issues to impose a DoS condition on the application. (CVE-2021-1971, CVE-2021-3449, CVE-2021-3450)
An information disclosure vulnerability exists in Visual Studio. An unauthenticated, remote attacker can exploit this to disclose potentially sensitive information. (CVE-2021-41355)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
