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.
