Microsoft has released 4 security bulletins to fix newly discovered flaws in their software. Qualys has released the following checks for these new vulnerabilities:
A remote code execution vulnerability exists in the Windows Bluetooth 2.1 Stack due to the way an object in memory is accessed when it has not been correctly initialized or has been deleted.
Affected Software:
Windows Vista Service Pack 1
Windows Vista Service Pack 2
Windows Vista x64 Edition Service Pack 1
Windows Vista x64 Edition Service Pack 2
Windows 7 for 32-bit Systems and Windows 7 for 32-bit Systems Service Pack 1
Windows 7 for x64-based Systems and Windows 7 for x64-based Systems Service Pack 1
Windows Vista x64 Edition Service Pack 1
Windows Vista x64 Edition Service Pack 2
Windows 7 for 32-bit Systems and Windows 7 for 32-bit Systems Service Pack 1
Windows 7 for x64-based Systems and Windows 7 for x64-based Systems Service Pack 1
Refer to Microsoft Security Bulletin MS11-053 for further details.
Workaround:
Stop and disable the Bluetooth driver by using the following command at the command prompt:
sc config bthport start= disabled
Microsoft Visio is prone to an insecure library loading vulnerability because the application loads libraries (e.g. mfc71enu.dll and mfc71loc.dll) in an insecure manner. This can be exploited to load arbitrary libraries by tricking a user into opening a Microsoft Visio Stencil (".vss") file located on a remote WebDAV or SMB share.
Affected Software:
Microsoft Visio 2003 Service Pack 3.
Microsoft Visio 2003 Service Pack 3
Refer to Microsoft Security Bulletin MS11-055 for further details.
Workaround:
1) Disable loading of libraries from WebDAV and remote network shares
2) Disable the WebClient service
Impact of workaround #2:When the WebClient service is disabled, Web Distributed Authoring and Versioning (WebDAV) requests are not transmitted. In addition, any services that explicitly depend on the Web Client service will not start, and an error message will be logged in the System log. For example, WebDAV shares will be inaccessible from the client computer.
3) Block TCP ports 139 and 445 at the firewall
Impact of workaround #3:Several Windows services use the affected ports. Blocking connectivity to the ports may cause various applications or services to not function.

Windows CSRSS is prone to multiple elevation of privilege vulnerabilities due to the way that it assigns memory for specific user transactions.
Microsoft has released a security update that addresses the vulnerabilities by not allowing multiple console objects to be associated with one process, by modifying the way the CSRSS initializes memory, by validating user input before use as an index for an array, and by modifying bounds checking to prevent memory corruption.
This security update is rated Important for all supported versions of Microsoft Windows.
