Microsoft released four security updates for various applications and operating systems that they produce. Three of the four updates are regarded as critical while one has a moderate risk level. To break it up further: Two patches are updating Microsoft Office 2000, Office XP, Office 2003 and Office 2007, one Windows XP, Windows 2000 and Windows Server 2003 and the last one applications that use the Microsoft Malware Protection Engine which includes Windows Live Care and Windows Defender.
Use the following links to open the Security Bulletins directly: Vulnerabilities in Microsoft Word Could Allow Remote Code Execution [link], Vulnerability in Microsoft Publisher Could Allow Remote Code Execution [link], Vulnerability in Microsoft Jet Database Engine Could Allow Remote Code Execution [link] and Vulnerabilities in Microsoft Malware Protection Engine Could Allow Denial of Service [link].
It is as always advised to update the system as soon as possible. The first two patches have to be applied to users of Microsoft Office, the third by almost everyone and the fourth by users who use Microsoft Malware protection applications.
