DESCRIPTION:
Two vulnerabilities have been reported in Microsoft Windows, which
can be exploited by malicious people to cause a DoS (Denial of
Service) and compromise a vulnerable system.

1) An error exists within the Windows DNS server when processing a
query for a NAPTR (Name Authority Pointer) resource record.

Successful exploitation of this vulnerability may allow execution of
arbitrary code, but requires that the server is setup as a
non-authoritative DNS server.

2) An error within the Windows DNS server when processing a query for
a non-existent domain can be exploited to cause the server to stop
responding.

SOLUTION:
Apply patches.
