Today, we are releasing the January 2020 Security and Quality Rollup Updates for .NET Framework.

Security

CVE-2020-0605, CVE-2020-0606, CVE-2020-0646 – .NET Framework Remote Code Execution

A remote code execution vulnerability exists when the Microsoft .NET Framework fails to validate input properly. An attacker who successfully exploited this vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

To learn more about the vulnerabilities, go to the following Common Vulnerabilities and Exposures (CVE).
