Microsoft Windows Distributed File System Memory Corruption Vulnerability

DFS Memory Corruption Vulnerability

An unauthenticated remote code execution vulnerability exists in the way that the Distributed File System (DFS) client parses specially crafted DFS responses. An attempt to exploit the vulnerability would not require authentication, allowing an attacker to exploit the vulnerability by sending a specially crafted DFS response to a client-initiated DFS request. An attacker who successfully exploited this vulnerability could execute arbitrary code and take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

DFS Referral Response Vulnerability

A denial of service vulnerability exists in the way that Microsoft Distributed File System (DFS) handles specially crafted DFS referral responses. An attempt to exploit the vulnerability would not require authentication, allowing an attacker to exploit the vulnerability by sending a specially crafted network message to a computer running the Server service.
