Security Updates for Microsoft Visual Studio Products (October 2021)

high Nessus Plugin ID 154051

Language:

Synopsis

The Microsoft Visual Studio Products are missing a security update.

Description

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.

Solution

Microsoft has released the following security updates to address this issue:
- Update 15.9.40 for Visual Studio 2017
- Update 16.4.27 for Visual Studio 2019
- Update 16.7.20 for Visual Studio 2019
- Update 16.9.12 for Visual Studio 2019
- Update 16.11.5 for Visual Studio 2019
