You cannot save documents to a folder or change the permission settings of folders on a SMB 1.0-based remote server from a Windows-based computer that has security update 980232 (MS10-020) installed

Applies To
Microsoft Windows XP Service Pack 2 Microsoft Windows XP Service Pack 3 Windows Vista Windows Vista Service Pack 2 Windows Server 2008 Windows Server 2008 Service Pack 2 Windows 7 Windows Server 2008 R2

Symptoms

You apply security update 980232 (MS10-020) on a computer that is running one of the following operating systems:

  • Windows 2000 Service Pack 4 (SP4)
  • Windows XP Service Pack 2 (SP2)
  • Windows XP Service Pack 3 (SP3)
  • Windows Server 2003 SP2
  • Windows Vista Service Pack 1 (SP1)
  • Windows Vista SP2
  • Windows Server 2008
  • Windows Server 2008 SP2
  • Windows 7
  • Windows Server 2008 R2

You may encounter one of the following issues when you use a remote server that is based on the Server Message Block (SMB) version 1 protocol. For example, you use a Windows NT Server 4.0 or other third-party servers, or a network storage device as the remote server.

Issue 1

You receive a “Document not saved” error message when you try to use a Microsoft Office application to save a document to the remote server.

Issue 2

You cannot use the built-in backup utility to save backup files to the remote server. For example, you cannot save backup files to the remote server when you use NTBackup in Windows XP or in Windows Server 2003.

Issue 3

The Security tab is missing when you examine the property of a folder on the remote server. Therefore, you cannot view or change the permission settings of folders on the remote server.

These issues may also occur if you do not use a SMB 1.0-based device, but use a Wide Area Network (WAN) optimizer instead. For example, you use Cisco wide area application services (WAAS) software.

Note The Server Message Block is more frequently known as the Common Internet File System (CIFS).

Cause

This issue occurs because security update 980232 (MS10-020) introduces a new validation for the security descriptors that are returned from the remote server. The validation calls the RtlValidRelativeSecurityDescriptor routine together with the security descriptor buffer and the length of the security descriptor buffer. For the length of the security descriptor buffer, the validation uses a field in the server response and assumes the field is set to the length of the security descriptor buffer correctly when the remote server responds with "STATUS_SUCCESS." However, the remote server returns 0 for the field. This behavior causes the validation to fail.

Resolution

After you apply the hotfix, the DataCount field of the server response is used as the length of the security descriptor buffer when the validation runs. This makes sure that the new validation succeeds when the SMB 1.0-based remote server returns "STATUS_SUCCESS."
