Microsoft readies patches for critical vulnerabilities affecting its Windows client and server operating systems, as well as components that ship by default with the platform. The Redmond company is wrapping up no less than seven security bulletins for an unspecified number of vulnerabilities impacting even Windows Vista and Windows XP, updated with Service Pack 1 and respectively Service Pack 3. The seven security bulletins are scheduled for delivery on June 10, 2008, in accordance with the Redmond company's monthly patch cycle.

"It is important to remember that while the information posted below is intended to help with your planning, because it is preliminary information, it is subject to change. As part of our regularly scheduled bulletin release, we're currently planning to release: three Microsoft Security Bulletins rated Critical, three Important, and one Moderate. As we do each month, the Microsoft Windows Malicious Software Removal Tool will be updated," revealed Bill Sisk, security response communications manager for Microsoft.

The three Critical security bulletins will impact both the 32-bit and 64-bit editions of Windows Vista RTM and SP1, Windows Server 2008, Windows Server 2003, Windows 2000 and Windows XP SP2 and SP3. The patches will address vulnerabilities which could allow for Remote Code Execution in the eventuality of successful exploits. According to Microsoft, the Bluetooth service is at risk, along with various versions of Internet Explorer, including 7, 6, 5.01 SP4, and DirectX 10, 9.08.1 and 7.0. Windows XP SP3 and Windows Vista SP1 contain all the high-risk security holes which will be patched by the Critical bulletin on June 10.

"Finally, we are planning to release high-priority, non-security updates on Windows Update and Windows Server Update Services (WSUS) as well as high-priority, non-security updates on Microsoft Update and Windows Server Update Services (WSUS)," Sisk added.
