DLL-Preloading remote attack vector

Thursday, August 26th, 2010

Microsoft released Security Advisory 2269637 notifying customers of a remote attack vector to a class of vulnerabilities affecting applications that load DLL’s in an insecure manner.

However, last week researchers published a remote attack vector for these issues, whereas in the past, these issues were generally considered to be local and relatively low impact. In a blog post, you find detailed information about a tool to protect systems.

 

Permission Issue with DFSN

Tuesday, August 24th, 2010

Accessing a folder under a mapped network drive to a Distributed File System Namespace (DFSN) folder target may fail on Windows Vista and and later OS versions with error “Access is Denied”.

Clients with Windows Vista or Windows 7 do not receive errors accessing the mapped folder, only its subfolders. Earlier versions of clients are able to successfully access the same subfolders without issue.

Accessing the subfolder from Windows Explorer will result in the following error message:

"You do not have permission to access \\dfsnroot\dfslinktarget\share. Contact your network administrator to request access."

Accessing the subfolder from the command prompt results in error "Access is denied."

The behavior is by-design, and is due to an additional check introduced with Windows Vista and Windows 7 Server Message Block (SMB) Protocol for permission on the target.

To resolve the issue, the subfolder permissions must allow "Traverse Folder/Execute File" for the user or group needing access.
