Security Updates for Microsoft .NET Framework (December 2018)

Critical Nessus Plugin ID 119612


The Microsoft .NET Framework installation on the remote host is affected by multiple vulnerabilities.


The Microsoft .NET Framework installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities :

- 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.

- A denial of service vulnerability exists when .NET Framework improperly handles special web requests. An attacker who successfully exploited this vulnerability could cause a denial of service against an .NET Framework web application. The vulnerability can be exploited remotely, without authentication. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to the .NET Framework application. The update addresses the vulnerability by correcting how the .NET Framework web application handles web requests. (CVE-2018-8517)


Microsoft has released security updates for Microsoft .NET Framework.
