In what could be described as a "quiet" month, Microsoft will issue just five security fixes this coming Patch Tuesday – with only one of them listed as "critical".

The patches will address problems in Windows, SharePoint, Visual Studio and Microsoft's instant messaging clients.
Two of the security updates – including the one listed "critical" – will be for Windows. The critical patch is for Windows 2000 SP4 and the other for Windows Services for Unix (SFU) which is incorporated into all versions of Windows, including Vista.
The other patches cover security issues in SharePoint Services 3.0 on Windows Server 2003, Visual Studio through Version 2005 SP1 and the MSN Messenger/Live Messenger Versions 6.2, 7.0, 7.5 and 8.0.
The release of this Patch Tuesday's five patches brings to 55 the number of patches issued by Microsoft so far this year, funnily enough, the same number for the corresponding period last year.
