Security Update for Visual Studio 2019 (June 2021) (macOS)

high Nessus Plugin ID 150988
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 remote host has an application installed that is affected by DoS vulnerability.

Description

The Microsoft Visual Studio 2019 runtime installed on the remote macOS or Mac OS X host is missing a security update. It is, therefore, affected by a denial of service vulnerability. When a .NET application utilizing libgdiplus on a non-Windows system accepts input, an attacker could send a specially crafted request that could result in application crashes.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version

Solution

Upgrade to Visual Studio 2019 version 8.10.0.1773 or later.
