Microsoft Windows Distributed File System Remote Code Execution Vulnerability

Microsoft Windows is prone to a remote code-execution vulnerability. The issue affects the Windows Distributed File System (DFS).

An attacker can exploit this issue by sending a specially crafted DFS response to the affected application.

Successfully exploiting this issue allows an attacker to execute arbitrary code in the context of the application, which may aid the attacker in taking complete control of an affected system.
