OVERVIEW:

        Microsoft will be releasing critical security patches for April 
        for their products on Wednesday 9 April 2008 at:

        4:00 am AEST (Queensland, ACT, NSW, Tasmania, Victoria)
        3:30 am ACST (SA, NT)
        2:00 am AWST (WA)

        Further details are available from the Microsoft web site [1].


DETAILS:

        Microsoft will be releasing eight security bulletins:

            - Two for Microsoft Office
            - One for Internet Explorer
            - One for JScript and VBScript
            - Four for various Windows operating systems

        Five of the vulnerabilities have been announced as having a critical 
        impact.


MITIGATION:

        AusCERT advises that system administrators consider patching their
        machines as quickly as possible following their release by Microsoft.
        Bulletin information will be available from the Microsoft web site
        soon after their release, and AusCERT will be distributing bulletins
        to AusCERT members on Wednesday.
  
        Historically, exploits targeting Microsoft vulnerabilities are
        released in the days immediately following their announcement, so it 
        is critical that system administrators apply patches or mitigate
        vulnerabilities as quickly as possible.
