Microsoft patches 12 critical flaws in office

Microsoft issued Tuesday four patches that fix 12 critical security vulnerabilities in Excel, Out-look, and other office components that attackers could exploit to take total control of affected PCs.
One zero-day flaw was also identified that hackers have already started exploiting, and another flaw could provide a pathway for infecting users with malicious ads served by otherwise secure Web sites.
The monthly patch roundup continues the trend that has seen hackers probing for flaws in client-side applications, instead of problems with servers.
