Microsoft will ship a critical update for its flagship web browser in a round of eight patches next week.
The browser contained critical remotely exploitable bugs that may be under active exploitation. It would be the eighth patch for Internet Explorer this year.
That fix will be shipped alongside a set of critical patches covering more remotely exploitable vulnerabilities in Microsoft Exchange Server versions 2013, 2010 and 2007 running Service Pack 3.
Administrators would likely need to patch the Outlook vulnerabilities as soon as possible given that the service would invariably be exposed to the internet.
Further remotely exploitable bugs rated critical were to be fixed in Windows XP and Windows Server 2003.
The remaining vulnerabilities to be patched were rated important and related to privilege escalation bugs, denial of service and information leakage.
An update for Microsoft's Malicious Software Removal Tool would also be released.
Microsoft would host a webcast to answer customer questions on the security bulletins on August 14. Register here.
