DESCRIPTION:
Two vulnerabilities have been reported in Microsoft Windows, which
can be exploited by malicious, local users to bypass certain security
restrictions and gain escalated privileges.

1) An error within the TCP/IP stack (tcpip.sys) does not properly
filter outbound packets when an outbound firewall rule is applied.
This can be exploited to bypass the Windows Firewall and send
otherwise restricted packets.

2) A double free error exists within the TCP/IP stack (tcpip.sys)
when handling IPv6 address binding on a local interface.

Successful exploitation of this vulnerability allows execution of
arbitrary code in context of another process.

NOTE: This vulnerability only affects Windows 7 and Windows Server
2008 R2.

SOLUTION:
Apply patches.
