As urgent as MS12-034 is, MS12-029 is also crucial. Kandek explains, "The bulletin provides a patch for a vulnerability in the RTF file format that can be exploited through Microsoft Office 2003 and 2007. It is rated critical because simply viewing an attached file in the preview pane of Microsoft Outlook is sufficient to trigger the exploit."

Of course, the rest of the security bulletins and patches should be addressed as well. The remaining five security bulletins fix flaws related to elevation of privileges and remote code execution, and should not be ignored or taken lightly.

Prioritize implementing the updates in MS12-034 and MS12-029, but be sure to review the other security bulletins and apply the patches as soon as possible.
