The highest severity rating for any of these flaws is "critical," according to Microsoft.
Four of the fixes will affect Windows, while the other will patch Microsoft Content Manager Server.
Microsoft will also release six non-security high priority updates as part of its regularly scheduled Patch Tuesday distribution.
Security researchers haven’t rested much since late last month when attacks on the Windows ANI flaw began.
Despite Tuesday’s early distribution, exploits continued to attack unpatched PCs this week, using pictures of Britney Spears and other lures as malware bait.
A number of sites containing iFrames, which permit the embedding of HTML documents inside a main document, are contributing to the spread of exploits, according to researchers.
The SANS Internet Storm Center and other research organizations have also reported problems with the Realtek HD Audio Control Panel after installation of the early patch.
Alexander Sotirov, researcher at Determina, the firm that first reported the flaw to Microsoft last year, said this week that Windows PCs with Firefox are also vulnerable to the flaw.
In the wake of the early release, a number of security researchers questioned whether Microsoft should change its patch release process.
