Microsoft plans to release 11 patches on Tuesday as part of its monthly fix cycle, the software giant announced today.

Six of the patches will address Windows flaws, while four will repair bugs in Office, according to a bulletin. At least two patches are designed to resolve critical vulnerabilities.

The remaining patch will address a moderate flaw in the .NET Framework, a software development platform for applications and web services.

Microsoft has acknowledged at least two zero-day exploits in the wild, affecting Internet Explorer (IE) and PowerPoint. Late last month, Redmond issued a rare out-of-cycle patch for a much publicized zero-day IE vulnerability caused by an error in the processing of vector markup language (VML).

Earlier this year, Microsoft released an out-of-cycle patch to fix the Windows metafile (WMF) vulnerability.

The return to double-digit patches is more of the norm for Microsoft, which saw a 12-patch release in August. Last month, though, the company only released three fixes.
