Synopsis

A distributed file system on the remote Windows host has multiple vulnerabilities.

Description

The Distributed File System (DFS) implementation running on the remote Windows host has the following vulnerabilities:

- The DFS client does not parse specially crafted DFS responses correctly, which could allow a remote, unauthenticated attacker to execute arbitrary code.
(CVE-2011-1868)

- The system does not properly handle specially crafted DFS referral responses, which could allow an unauthenticated, remote attacker to cause a denial of service. (CVE-2011-1869)

Solution

Microsoft has released a set of patches for Windows XP, 2003, Vista, 2008, 7, and 2008 R2.
