Microsoft released eight security patches yesterday, including five patches to fix “critical” holes in Windows, Internet Explorer, Exchange Server, MSN Messenger and Microsoft Word.
All five critical vulnerabilities could allow an attacker to take complete control of users’ systems, said Microsoft.
The other three vulnerabilities also allow an attacker to possibly take control of machines but are only classed as “important” by Microsoft.
Microsoft is also releasing two non-security updates marked as “high priority” through Windows Update.
And Microsoft is also re-releasing two security bulletins, MS05-002 for users running Windows 98, 98 Second Edition and Windows ME, and MS05-009 for users running Windows Messenger.
Customers who have already deployed Windows Server 2003 SP1 do not need to apply the Windows updates released yesterday.
