Vulnerability Information

.NET Framework Remote Code Execution Vulnerability - CVE-2016-0148

A remote code execution vulnerability exists when Microsoft .NET Framework 
fails to properly validate input before loading libraries. 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 exploit the vulnerability, an attacker would first need to access the local
system with the ability to execute a malicious application. The security 
update addresses the vulnerability by correcting how .NET validates input on 
library load.

The following table contains links to the standard entry for each 
vulnerability in the Common Vulnerabilities and Exposures list:
