Security Updates for Microsoft Visual Studio Products (October 2021)

high Nessus Plugin ID 154051
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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
