The updates will be issued Tuesday as part of Microsoft's regularly scheduled monthly patching process.

Engineers are still working on a fix for a zero-day vulnerability in Internet Explorer being actively targeted in drive-by attacks. Microsoft issued an advisory on Tuesday warning of a memory allocation error, present in Internet Explorer 6, 7, and 8 could enable an attacker to execute code and gain access to a victim's machine.
