| Business Impact: |
This vulnerability is in a core component of most modern Microsoft Windows operating systems, including server editions. If crafted properly, the attack would provide full remote code execution without any end user interaction, although a denial-of-service is more likely to occur. However, the attacker must first have authentication rights to the system, and the guest account would not work in this scenario. |

| Technical Description: |
Microsoft Windows could allow a remote authenticated attacker to execute arbitrary code on the system, caused by the improper handling of malicious SMB responses within the pathname by the Microsoft Server Message Block (SMB) Protocol software. By sending a specially-crafted SMB packet to a computer connected to an SMB Server, a remote attacker could exploit this vulnerability to execute arbitrary code on the system. |
| Remediation: |
Patches are available. See References for details. |
