The bulletins, affecting the Microsoft Windows operating system, have a maximum severity rating of "critical" and will require a restart, the Redmond, Wash.,-based computing giant said on its website.
The company will also release an updated version of its malicious software-removal tool through Windows Update, Microsoft Update, the Windows Server Update Services and the Download Center.
A Microsoft spokesperson said on Monday that the company had no new information about the updates to release.
Last month, Microsoft released a single patch, containing three separate updates, that addressed problems with either Windows Media Format or Enhanced Media Format. Before the November release, Microsoft also said that update would have a critical rating.
