Microsoft Patch Tuesday Fixes 11 Flaws

Microsoft has rolled out three security bulletins for this weeks Patch Tuesday update, including fixes for 11 vulnerability affecting Microsoft Office.

The software giant, which releases bulletins every month to fix vulnerabilities in its software, has this time turned its focus more on Office than any other software.

Only one bulletin is rated as critical, while the other two are rated as important.

According to PC World, the critical security bulletin will cover flaws in Microsoft Office 2007 and 2010.

Joshua Talbot, security intelligence manager at Symantec Intelligence Response, said that Word is one of the most vulnerable features in Office, and as Outlook uses Word to open e-mail content, users can be targeted by hackers who use malicious RTF files to gain access.

The second security bulletin mainly addresses vulnerabilities in PowerPoint and is rated as important by Microsoft.

The third security bulletin, which is also rated as important, addresses four Forefront Unified Gateway vulnerabilities.

This particular set of patches does not cover the recent zero-day vulnerability in Internet Explorer browser, which still remains unpatched.
