medium Nessus Plugin ID 155018

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:

 - A denial of service (DoS) vulnerability exists in the OpenSSL component of Visual Studio. An unauthenticated, remote attacker can exploit this issue to cause the application to stop responding. (CVE-2020-1971)

 - Multiple A privilege escalation vulnerabilities exist in Visual Studio. An unauthenticated, local attacker can exploit thees to gain privileged access to the system. (CVE-2021-42277, CVE-2021-42319)

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 15.9.41 for Visual Studio 2017
 - Update 16.7.21 for Visual Studio 2019
 - Update 16.9.13 for Visual Studio 2019
 - Update 16.11.6 for Visual Studio 2019
