Today, we are releasing the September 2018 Security and Quality Rollup.

Security

CVE-2018-8421 – Windows Remote Code Execution Vulnerability

This security update resolves a vulnerability in Microsoft .NET Framework that could allow remote code execution when .NET Framework processes untrusted input. An attacker who successfully exploits this vulnerability in software by using .NET Framework could take control of an affected system. The attacker could then install programs; view, change, or delete data; or create new accounts that have full user rights. Users whose accounts are configured to have fewer user rights on the system could be less affected than users who operate with administrative user rights.

CVE-2018-8421
