DESCRIPTION:
Two vulnerabilities have been reported in Microsoft Windows, which
can be exploited by malicious, local users to gain escalated
privileges and by malicious people to cause a DoS (Denial of
Service).

1) An error in the TCP/IP stack can be exploited via a small number
of IPv6 packets with specially crafted extension headers to cause a
vulnerable system to stop responding. 

Successful exploitation requires that IPv6 features are enabled
(enabled by default in Windows Vista and Windows Server 2008).

2) An integer overflow error in the TCP/IP stack when processing a
specific input buffer can be exploited by a local user to execute
arbitrary code with system-level privileges.

SOLUTION:
Apply patches.
