Microsoft plans to release 13 sets of security patches this Tuesday fixing critical vulnerabilities in a number of its products, including the company's new security software.
The bulk of the patches will fix flaws in the Windows operating system and Office, Microsoft said in a statement published on its website. Five of the updates will be for Windows and two of them will be for Office. Microsoft also plans to release one less critical update that addresses flaws in both Windows and Office.
The patches will be released as part of Microsoft's monthly cycle of security updates.
There will also be patches for Microsoft's Step-by-Step Interactive Training, Microsoft Data Access Components, and an update that covers both Windows and Visual Studio.
Finally, Microsoft will also publish an update that patches critical flaws in its Windows Live OneCare, Antigen, Windows Defender, and ForeFront security software.
The Office patches have been anticipated, as online criminals have been exploiting unpatched vulnerabilities in Word and Excel for several months now. These attacks, which are occurring on a limited scale according to Microsoft, try to trick the victim into opening a maliciously coded Office attachment in order to compromise the PC.
