For those who need to prioritize deployment, Microsoft recommends focusing on MS13-059 and MS13-60 first.

MS13-059 | Cumulative Security Update for Internet Explorer

This security update resolves eleven privately disclosed issues in Internet Explorer, for which we have not detected any attacks or customer impact. All issues 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. This security update is rated Critical for all versions of Internet Explorer.

MS13-060 | Vulnerability in Unicode Scripts Processor Could Allow Remote Code Execution

This security update resolves one issue in Windows that could allow remote code execution if a customer views a specially-crafted document or web page. An attacker who successfully exploited these vulnerabilities could gain the same rights as the logged-on user. This security update is rated Critical for Windows XP and Windows Server 2003. This issue was privately disclosed and we have not detected any attacks or customer impact.

Security Advisory 2861855 - Updates to Improve Remote Desktop Protocol Network-level Authentication

This update adds defense-in-depth measures to the Network Level Authentication (NLA) technology within the Remote Desktop Protocol in Microsoft Windows.

Security Advisory 2862973 - Update for Deprecation of MD5 Hashing Algorithm for Microsoft Root Certificate Program

This update impacts applications and services using certificates with the MD5 hashing algorithm. This restriction is limited to certificates issued under roots in the Microsoft root certificate program. This will apply only to certificates utilized for server authentication, code signing and time stamping. These applications and services will no longer trust certificates utilizing MD5 and we will release this change via Microsoft Update in February 2014.

Two bulletins are re-releases affecting MS13-052 and MS13-057. Both of these re-releases address certain application compatibility issues discovered after the bulletins were initially released. Microsoft recommends all customers apply the new updates that apply to their systems. Those that have automatic updating enabled will not need to take any action.
