Microsoft last night released Security Advisory 927891, to address a memory leak when Windows Update or Microsoft Update is scanning for updates that use Windows Installer.
Your system may appear to become unresponsive when Windows Update or Microsoft Update is scanning for updates that use Windows installer, and you may notice that the CPU usage for the svchost process is showing 100%.
When you try to install an update from Windows Update or from Microsoft Update, you experience the following symptoms:
• Your system may appear to become unresponsive when Windows Update or Microsoft Update is scanning for updates that use Windows Installer.
• You receive an access violation error in svchost.exe. This access violation stops the Server service and the Workstation service.
• A memory leak occurs when Windows Update or Microsoft Update is scanning for updates that use Windows Installer.
• Windows Update or Microsoft Update scans take a very long time, sometimes hours, to complete.
This fix is one component of a two-part fix that includes a Windows Update client software update. These updates will be deployed automatically using Windows Update in May 2007 and June 2007. However, some customers may select to manually install these updates. To fully address the unresponsive system issue, both this fix for MSI must be installed and the Windows Update client must be updated to version 3.0.
