Vulnerability Information

Windows Firewall Bypass Vulnerability - CVE-2012-0174

A security feature bypass vulnerability exists in Windows due to the way that 
Windows Firewall handles outbound broadcast packets. An attacker who 
successfully exploited this vulnerability could bypass the Windows Firewall 
defense-in-depth mechanism to facilitate exploitation of other 
vulnerabilities.

To view this vulnerability as a standard entry in the Common Vulnerabilities 
and Exposures list, see CVE-2012-0174.

TCP/IP Double Free Vulnerability - CVE-2012-0179

An elevation of privilege vulnerability exists in the Windows TCP/IP stack 
that affects Windows 7 and Windows Server 2008 R2. All editions of Microsoft 
Windows XP, Windows Server 2003, Windows Vista, and Window Server 2008 are not
affected. This vulnerability is caused when the Windows TCP/IP stack fails to 
properly handle the binding of IPv6 addresses.

To view this vulnerability as a standard entry in the Common Vulnerabilities 
and Exposures list, see CVE-2012-0179.
