For those who need to prioritize deployment, Microsoft recommends focusing on MS13-021, MS13-022 and MS13-027 first:

MS13-021 (Microsoft Internet Explorer)

This security update resolves nine issues in Internet Explorer. The most severe vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited these vulnerabilities could gain the same rights as the current owner. All but one of these issues were privately disclosed and we have not detected any attacks or customer impact for any of the issues.

MS13-022 (Microsoft Silverlight)

This security update resolves an issue Microsoft Silverlight. The vulnerability could allow remote code execution if an attacker hosts a website that contains a specially crafted Silverlight application that could exploit this vulnerability and then convinces a user to view the website. This issue was privately reported and we have not detected any attacks or customer impact.

MS13-027 (Kernel Mode Drivers)

This security update resolves three issue in Microsoft Windows. These vulnerabilities could allow elevation of privilege if an attacker gains access to a system. In a default configuration, an unauthenticated attacker could only exploit this vulnerability if they have physical access to the system. Again, these issues were privately reported and we have not detected any attacks or customer impact.
