Patch Tuesday offers up fixes for four security holes, all of which have been deemed 'critical.' If you don't have automatic updates on, I suggest you hit the Windows Update button and get your patch on. The updates fix nine bugs in Microsoft's products. In addition to the four critical updates, Microsoft also released 'important' fixes for the Windows SharePoint collaboration software and in the Windows RPC (remote procedure call) technology.

- MS07-055 addresses a vulnerability in Kodak Image Viewer, and is rated as a Critical bulletin.
- MS07-056 addresses a vulnerability Outlook Express and Windows Mail, and is rated as a Critical bulletin.
- MS07-057 is a Cumulative Security Update for Internet Explorer, and is rated as a Critical bulletin.
- MS07-058 addresses a vulnerability in RPC, and is rated as an Important bulletin.
- MS07-059 addresses a vulnerability in Windows SharePoint Services 3.0 and Office SharePoint Server 2007, and is rated as an Important bulletin.
- MS07-060 addresses a vulnerability in Microsoft Word, and is rated as a Critical bulletin

In addition to the bulletins mentioned above, Microsoft also re-released bulletin MS05-004. This re-release updates detection includes Server 2003 Service Pack 2 and Vista as affected platforms. There were no changes to the update binaries, so if you have already successfully installed this update, you do not need to reinstall it. Customers who have applied MS07-040 are unaffected by this detection update, as their systems are up-to-date from a .NET Framework security stance.
