Microsoft yesterday issued two security updates for its Windows and Office products, including a patch that fixes critical vulnerabilities in the Office collaboration suite.
The Office update fixes holes in a variety of Office products, including Microsoft Office XP, Office 2003, Works Suite and Office X for the Mac.
But the "critical" security rating only applies to the Office 2000 solution, said Microsoft, as the threat could be exploited without any user interaction.
Office 2000 users could theoretically have their computers taken over by remote attackers if they clicked on a malicious file.
But users of other Office products would not be as open to such an attack as they would have to click through an additional dialogue box before becoming compromised, said Microsoft.
Most of the bugs that affect Office relate to the Excel spreadsheet contained in the software suite. The less threatening Windows vulnerability could allow an attacker to change the privileges of services running on Windows.
This bug only affects users running Windows XP Service Pack 1 and Windows Server 2003. Updated versions are not affected.
