Microsoft has released a patch that eliminates the "Netmon Protocol Parsing" vulnerability in Microsoft Windows NT and 2000 server and SMS which allows remote users to gain control of an affected server. Protocol parsers in Network Monitor (Netmon) contain unchecked buffers which allow malicious users to execute arbitrary code by sending a malformed frame to a server which is monitoring traffic. Microsoft FAQ on this issue available here.

Patch Available for "Netmon Protocol Parsing" Vulnerability

Originally posted: November 01, 2000

Summary
=======
Microsoft has released a patch that eliminates a security
vulnerability in Microsoft(r) Windows NT(r) and Windows(r) 2000
server products and Systems Management Server. The vulnerability
could allow a malicious user to gain control of an affected server.

Frequently asked questions regarding this vulnerability and
the patch can be found at
http://www.microsoft.com/technet/security/bulletin/fq00-083.asp

Issue
=====
Microsoft ships two versions of Network Monitor (Netmon): a basic
version that ships with Windows NT 4.0 and Windows 2000 server
products, and full version that ships as part of Systems Management
Server (SMS) 1.2 and 2.0. Both versions include protocol parsers that
aid administrators in interpreting and analyzing previously-captured
network data. However, several of the parsers have unchecked buffers.
If a malicious user delivered a specially-malformed frame to a server
that was monitoring network traffic, and the administrator parsed it
using an affected parser, it would have the effect of either causing
Netmon to fail or causing code of the malicious user's choice to run
on the machine.

Netmon requires administrative privileges to run, but should only be
run by local, rather than domain, administrators. If this is done,
the vulnerability could be used to gain complete control over the
local machine, but could not be used to gain control over a domain.
Netmon does not ship on workstation products, so unless SMS had been
installed on a workstation, it would not be affected by this
vulnerability.

Affected Software Versions
==========================
- Microsoft Windows NT 4.0 Server
- Microsoft Windows NT 4.0 Server, Terminal Server Edition
- Microsoft Windows NT 4.0 Server, Enterprise Edition
- Microsoft Windows 2000 Server

- Microsoft Windows 2000 Datacenter Server
- Microsoft Systems Management Server 1.2
- Microsoft Systems Management Server 2.0

Note: Netmon does not ship as part of Windows NT 4.0 Workstation or
Windows 2000 Professional. These products would only be affected if
SMS had been installed on them.
