2. Episode Thirteen: Cabbages and Kings
by Robert G. Ferrell
Jake sat at the incarcerated Merv's terminal and scratched his head. The
military security people had told him that this box was sending bursts of
(presumed) classified data to an undisclosed location in another country.
Okay, except that this segment of the network had no physical attachment
to the secured net. In fact, the segment into which this box was plugged
wasn't even on his network map. That was a little disturbing, but not
entirely surprising , since the data telecomm documentation he'd inherited
from his predecessor was a little on the skimpy side.

II. BUGTRAQ SUMMARY
-------------------
1. Microsoft UPnP NOTIFY Buffer Overflow Vulnerability
BugTraq ID: 3723
Remote: Yes
Date Published: Dec 20 2001 12:00A
Relevant URL:
http://www.securityfocus.com/bid/3723
Summary:
Universal Plug and Play, or UPnP, is a service that allows for hosts to
locate and use devices on the local network. UPnP support ships with
Windows XP and ME. For Windows 98 and 98SE, it is available with Windows
XP's Internet Connection Sharing client.
When a new device is installed, it will broadcast a UDP NOTIFY packet to
all devices on the UPnP network specifying the address and port for all
other devices to download its description from. This information is
stored in the location field, one of several comprising the NOTIFY
message.
When processing the location field in a NOTIFY directive, UPnP server
process memory can be overwritten by data that originated in the packet.
If the IP address, port and filename components are of excessive length,
access violations will occur when the server attempts to dereference
pointers overwritten with data from the packet.
This condition may be exploitable in a number of different ways, depending
on what is overwritten by attackers. An attacker may be able to overwrite
a function pointer with a pointer to shellcode also supplied in the
request. An attacker may also be able to replace a pointer that is
written to, and the value that is written. This could allow for code
execution through replacement of return addresses, function pointers, etc.
It should be noted that the service listens on broadcast and multicast
interfaces. This could permit an attacker to exploit a number of systems
without knowing their individual IP addresses.
The UPnP service runs in the SYSTEM security context. An attacker who
successfully exploits this vulnerability could gain control over the
target host.
2. Microsoft Internet Explorer Refresh Denial of Service Vulnerability
BugTraq ID: 3730
Remote: Yes
Date Published: Dec 20 2001 12:00A
Relevant URL:
http://www.securityfocus.com/bid/3730
Summary:
A malicious web site operator could design a web page that, when visited
by an IE user, will cause IE to crash.
If a webpage containing Javascript designed to cause a continuous refresh
via 'self.location = self.location' is viewed, IE will crash.
A restart of the application is required in order to gain normal
functionality.
3. Microsoft IE for Solaris X Server Denial of Service Vulnerability
BugTraq ID: 3729
Remote: No
Date Published: Dec 20 2001 12:00A
Relevant URL:
http://www.securityfocus.com/bid/3729
Summary:
It has been reported that in some situations, Internet Explorer 5.0 SP1
for Solaris is able to crash the X server. In particular, this has been
reported with Chinese versions of the software.
If a chinese language web page is displayed, and the IE window is rapidly
scrolled up and down, it is possible to end the user session, returning
the CDE session to dtlogin. This may also happen if the IE window is
maximized.
If this procedure is repeated several times, the X server may crash
altogether. At this point, the local user is simply presented with a text
login prompt, and the following message:
can not start x server
This problem can result in a denial of service to all X users.
4. Microsoft SQL-Server Buffer Overflow Vulnerability
BugTraq ID: 3733
Remote: Yes
Date Published: Dec 20 2001 12:00A
Relevant URL:
http://www.securityfocus.com/bid/3733
Summary:
Microsoft SQL Server contains buffer overflows in several built-in text
formatting and printing functions. Two of the affected functions
are 'raiserror()' and 'xp_sprintf()', both vulnerable to overflows due to
inadequate bounds checking of externally supplied data prior to memory
copy operations. If the amount of data supplied exceeds the size of the
buffer where it is to be copied, the excessive data will overwrite
neighbouring memory. If critical data such as the function return address
on the stack is overwritten, the flow of program execution can be
altered.
If an attacker can invoke the affected procedures with
custom arguments, or insert/modify arguments for legitimate invocations,
arbitrary code can be executed. This can be accomplished by replacing the
affected function return address with a pointer to supplied shellcode.
It may be possible for malicious users to exploit this
vulnerability through applications that interact with the database, such
as CGI scripts or Java programs. Public domain CGI scripts are
notoriously ridden with input validation vulnerabilities that may allow
for attacker insertion of exploit code into SQL queries.
This vulnerability makes it possible for an attacker to execute arbitrary
code in the security context of the server process. An attacker can also
exploit this vulnerability to crash the server.
5. Microsoft Universal Plug and Play Simple Service Discovery Protocol
Denial of Service Vulnerability
BugTraq ID: 3724
Remote: Yes
Date Published: Dec 20 2001 12:00A
Relevant URL:
http://www.securityfocus.com/bid/3724
Summary:
Universal Plug and Play, or UPnP, is a service that allows for hosts to
locate and use devices on the local network. UPnP support ships with
Windows XP and ME. For Windows 98 and 98SE, it is available with Windows
XP's Internet Connection Sharing client.
The Simple Service Discovery Protocol (SSDP) is a component of UPnP that
allows a system to enumerate the resources of a newly installed network
device on a UPnP network. When a new device is installed, it will
broadcast a UDP NOTIFY packet to all devices on the UPnP network
specifying the address and port for all other devices to download its
description from.
It is possible to construct a UDP NOTIFY packet that will direct UPnP
devices to download the description from a port on a system which echoes
the requests, the requesting UPnP systems could enter an endless download
cycle. The system could be manually restarted to exit this condition.
It has been reported that in some situations, Internet Explorer 5.0 SP1
for Solaris is able to crash the X server. In particular, this has been
reported with Chinese versions of the software.
It could also be possible to use this technique to initiate a distributed
denial of service attack on a third party. By constructing a NOTIFY
packet which directs a large number of UPnP devices to the address of a
third party server, the responding UPnP devices could flood the server
with requests.
For both scenarios, the NOTIFY packet could be directed to a broadcast or
multicast domain which would affect all the UPnP systems within earshot
with a single packet.
6. Microsoft Windows C Runtime Library Format String Vulnerability
BugTraq ID: 3732
Remote: Unknown
Date Published: Dec 20 2001 12:00A
Relevant URL:
http://www.securityfocus.com/bid/3732
Summary:
The Windows C Runtime Library is a shared library containing instructions
for the standard C library functions. It is used by almost all Windows
programs compiled from C or C++ source code.
There exists a format string vulnerability in the Windows C Runtime
Library that may be exploitable through programs that use the affected
functions.
Format string vulnerabilities typically occur in applications that pass
user input to library functions supporting *printf string formatting as
the format string argument. When users can control the format string,
special format specifiers such as '%n' can be used to write almost
arbitrary values to attacker-supplied locations in memory.
In existing format string vulnerabilities, the problem is that the
application fails to properly sanitize data before passing it to the
*printf function. This vulnerability is different, and lies in the
library code rather than in a specific application.
It is reportedly possible for attackers who can pass data to the affected
functions in programs using them to exploit this vulnerability.
It has been confirmed that this vulnerability is exploitable through SQL
Server, however the only possible consequence of a successful attack is a
denial of service (code execution is reportedly not possible).

V. NEW TOOLS FOR MICROSOFT PLATFORMS
------------------------------------
1. Stunnel v3.22
by Michal Trojnara, Michal.Trojnaracentertel.pl
Relevant URL:
http://stunnel.mirt.net/
Platforms: FreeBSD, Linux, Windows 2000, Windows 95/98, Windows NT
Summary:
The stunnel program is designed to work as an SSL encryption wrapper
between remote client and local (inetd-startable) or remote server. It can
be used to add SSL functionality to commonly used inetd daemons like POP2,
POP3, and IMAP servers without any changes in the programs' code. It will
negotiate an SSL connection using the OpenSSL or SSLeay libraries. It
calls the underlying crypto libraries, so stunnel supports whatever
cryptographic algorithms you compiled into your crypto package. This
release includes a timeout for the transfer() function, and a fix for a
coredump on exit with active threads.
2. Big Brother 1.8d2
