Redmond-based software giant Microsoft has recently announced that this September, as part of its Patch Tuesday program, it will roll out 5 security bulletins to its customers all over the world. All five bulletins carry the same severity rating – that would be 'important'. They are meant to address vulnerabilities that could lead to remote code execution or elevation of privilege.

Speaking of vulnerabilities, the five security bulletins Microsoft will release will plug a grand total of 15 vulnerabilities. These vulnerabilities plague the Microsoft Windows operating system, the Microsoft Office productivity suite, and Microsoft Sever Software.

As a little reminder, Microsoft uses the 'important' rating when it faces a vulnerability that if exploited by the bad guys, could compromise the confidentiality, integrity, or availability of the user’s data or it could compromise the integrity or availability of processing resources.

If you’re not familiar with Microsoft’s Patch Tuesday program, here’s the lowdown: every second Tuesday of the month, Microsoft rolls out patches for its products; the patches are meant to address various problems that may plague Microsoft products. As part of the September 2011 Patch Tuesday, the abovementioned five security bulletins will be released on the 14th of September, at about 10AM PDT.

Microsoft has released an advance notification for the September 2011 Patch Tuesday that provides a little bit more info on the security bulletins that will be released. You can view the advance notification by clicking this link.

In related news, back in August Microsoft released 13 security bulletins as part of the Patch Tuesday program. These bulletins addressed 22 vulnerabilities that affected the Windows operating system, the Internet Explorer web browser, the .NET Framework, and the integrated development environment (IDE) Visual Studio. Two of the 13 bulletins were rated 'critical', 9 were rated 'important' and 2 were rated 'moderate.'
