Microsoft Windows SMBv2 Multiple Vulnerabilities( 14 October 2009 )
RISK: Medium Risk
1. SMBv2 Infinite Loop Vulnerability
A denial of service vulnerability exists in the way that Microsoft Server Message Block (SMB) Protocol software handles specially crafted SMB version 2 (SMBv2) packets. An attempt to exploit the vulnerability would not require authentication, allowing an attacker to exploit the vulnerability by sending a specially crafted network message to a computer running the Server service. An attacker who successfully exploited this vulnerability could cause the computer to stop responding until restarted.
2. SMBv2 Command Value Vulnerability
An unauthenticated remote code execution vulnerability exists in the way that Microsoft Server Message Block (SMB) Protocol software handles specially crafted SMB packets. An attempt to exploit the vulnerability would not require authentication, allowing an attacker to exploit the vulnerability by sending a specially crafted network message to a computer running the Server service. An attacker who successfully exploited this vulnerability could take complete control of the system.
3. SMBv2 Negotiation Vulnerability
An unauthenticated remote code execution vulnerability exists in the way that Microsoft Server Message Block (SMB) Protocol software handles specially crafted SMB packets. An attempt to exploit the vulnerability would not require authentication, allowing an attacker to exploit the vulnerability by sending a specially crafted SMB packet to a computer running the Server service. An attacker who successfully exploited this vulnerability could take complete control of the system.
