Microsoft Security Bulletin MS12-020 - Critical

Vulnerabilities in Remote Desktop Could Allow Remote Code Execution (2671387)

   Published: Tuesday, March 13, 2012

   Version: 1.0

General Information

Executive Summary

   This security update resolves two privately reported vulnerabilities in
   the Remote Desktop Protocol. The more severe of these vulnerabilities
   could allow remote code execution if an attacker sends a sequence of
   specially crafted RDP packets to an affected system. By default, the
   Remote Desktop Protocol (RDP) is not enabled on any Windows operating
   system. Systems that do not have RDP enabled are not at risk.

   This security update is rated Critical for all supported releases of
   Microsoft Windows. For more information, see the subsection, Affected
   Software, in this section.

Vulnerability Information

Remote Desktop Protocol Vulnerability - CVE-2012-0002

   Desktop Protocol accesses an object in memory that has been improperly
   initialized or has been deleted. An attacker who successfully exploited
   this vulnerability could run abitrary code on the target system. An
   attacker could then install programs; view,change, or delete data; or
   create new accounts with full user rights.

Terminal Server Denial of Service Vulnerability - CVE-2012-0152

   A denial of service vulnerability exists in the way that the Remote
   Desktop Protocol service processes packets. An attacker who
   successfully exploited this vulnerability could cause the target
   service to stop responding.
