For those who need to prioritize deployment, Microsoft recommends focusing on MS13-028 and MS13-029 first.

MS13-028 (Microsoft Internet Explorer)
This security update resolves two issues in Internet Explorer, both of which could allow remote code execution if a customer views a specially crafted webpage using the browser. An attacker who successfully exploited these vulnerabilities could gain the same rights as the current user. Both of these issues were privately disclosed and we have not detected any attacks or customer impact.

MS13-029 (Windows Remote Desktop Client)
This security update resolves an issue in the Windows Remote Desktop Client ActiveX control. The vulnerability could allow remote code execution if an attacker convinces a customer to view a website containing specially crafted content that exploits the vulnerability. This issue was privately reported and we have not detected any attacks or customer impact.
