Microsoft announced plans on Thursday to issue four "critical" security bulletins next week that address vulnerabilities in its Windows Mail, Internet Explorer and Windows XP.
The bulletins, which total six, include four critical fixes, according to Microsoft's advance advisory notification. Microsoft aims to fix "critical" security flaws in Windows, Internet Explorer, Outlook Express and Windows Mail in Vista.
"Critical" is the most severe ranking Microsoft assigns to security flaws, which typically indicates a system can be compromised remotely with little interaction required by the user.
Specifically, Windows XP Service Pack 2, Windows Server 2003, IE 5.01 running on Windows 2000 with SP4 and Windows Mail in Vista are among the affected software.
Ironically, Microsoft has touted Vista as its most secure version of Windows to date, but even last April the software giant had to issue an emergency update that fell out of its usual monthly patch cycle.
The security update is designed to address Windows Mail in Windows Vista and Windows Vista x64.
