Microsoft releases 'critical' security patches
Microsoft released five security bulletins to fix flaws that could allow an attacker to take complete control of someone else’s computer system.
The security flaws rated “critical”—Microsoft’s highest threat level—affect the company’s Windows computer operating system, Internet Explorer browser, MSN Messenger, Microsoft Word software and Exchange server system.
The software maker also released three other patches on Tuesday to fix Windows flaws that carry less of a security threat. But the company said those “important” bulletins also could allow a malicious user to take control of another person’s computer.
All the flaws affect computers with operating systems dating back to Windows 98.
Users who have installed Microsoft’s massive security update for Windows XP, Service Pack 2, also will need to install some patches.
