OVERVIEW

        Microsoft will be releasing critical security patches for July for 
        their products on Wednesday 15 July 2009 at:
        
               4:00 am - AEST (ACT, NSW, Queensland, Tasmania, Victoria)
               3:30 am - ACST (SA, NT)
               2:00 am - AWST (WA)
        
        Further details are available from the Microsoft web site [1].


IMPACT

        Microsoft will be releasing six security bulletins:
        
        Critical:
        	- three for Windows
        
        Important:
        	- one for Virtual PC, Virtual Server
        	- one for Microsoft ISA Server
        	- one for Microsoft Office


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.
        
        These vulnerabilities are currently being exploited, so it is critical 
        that system administrators apply patches or mitigated vulnerabilities 
        as quickly as possible.
