CVE-2012-0174

Windows Firewall in tcpip.sys in Microsoft Windows Vista SP2, Windows Server 2008 SP2, R2, and R2 SP1, and Windows 7 Gold and SP1 does not properly enforce firewall rules for outbound broadcast packets, which allows remote attackers to obtain potentially sensitive information by observing broadcast traffic on a local network, aka "Windows Firewall Bypass Vulnerability."
