DETAILS:

       Microsoft will be releasing ten security bulletin:

       Critical:
           - Two for Windows
           - One for Internet Explorer
           - One for Word
           - One for Excel
           - One for Office

       Important:
           - Three for Windows

       Moderate:
           - One for Windows
       

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.
