SMALL BUSINESSES, BIG SECURITY RISKS
According to a survey released by analyst GartnerGroup smaller companies
particularly lack the security expertise necessary to fend off computer
attackers. Its research suggests that, without taking immediate steps
to remedy the situation, 50 percent of these businesses will be the victim
of a successful hack or a damaging virus outbreak in the next couple of years.

WATCH OUT FOR MALICIOUS HTML PAGES
Recently discovered security hole in Internet Explorer 5 (allowing for not
signed ActiveX components to perform malicious actions on PC) led to
invention of new virus callec GODMESSAGE. The computer can be infected
by simply viewing the web page, containing the Active X applet. Message
from the creators : "godmessageIV.html - view, get rooted. It is a modified
tHing 1..6 server without ICQ notification, without hide process (so it will
run on NT/w2k). A fellow named splyc took out the ICQ notification which
I got from blade's forums. I took out the hide process function because it
was not allowing the tHing to run on NT or 2k. The tHing listens on port
7777 and the password is pass."

FIREWALLS
"Simply put, a Firewall is a system that prevents unauthorized access to
or from a private network by examining the incoming packets and/or
requests coming from (in this case) the Internet. Here�s an analogy, let�s
say a firewall is like a bouncer at a 21 and over bar called MyNetworkRocks,
and the unauthorized InternetGuru is under 21. Well, because InternetGuru
is under 21 he�s not getting past the firewall (bouncer) into MyNetworkRocks,
at least not easily. Firewalls can be setup with software, hardware, or both,
depending on how paranoid, I mean secure, you want to be."

INTERPOL ORDERS IMMEDIATE CYBERCRIME ACTION
The head of Interpol has warned nations, law enforcement groups and
companies to act swiftly if they are to stand any chance of beating
cybercrime. Speaking at a conference in London Wednesday, Raymond
Kendall, secretary general of Interpol said his organisation is concerned
that unlawful computer techniques are developing at such a rate that
they represent a "new phenomenon" for international law enforcers. Kendall
urged international organisations not to wait for conventions to be passed
before drawing up guidelines for an allied response to the threat of cybercrime.

MASTER INDEX TRAVERSE ADVISORY
Synnergy Labs has found a flaw within Master Index that allows a user to
successfully traverse the filesystem on a remote host, allowing arbitary
files/folders to be read.

DEBIAN LINUX - NEW VERSIONS OF BOA PACKAGES
In versions of boa before 0.94.8.3, it is possible to access files outside of the
server's document root by the use of properly constructed URL requests.
This problem is fixed in version 0.94.8.3-1, uploaded to Debian's unstable
distribution on October 3, 2000. Fixed packages are also available in proposed
updates and will be included in the next revision of Debian/2.2 (potato).
Link: http://www.net-security.org/text/bugs/971179295,4133,.shtml
DEBIAN LINUX - ESOUND PACKAGE IS NOT AFFECTED
Linux-Mandrake has recently released a Security Advisory covering a race
condition in the esound.
Link: http://www.net-security.org/text/bugs/971179403,38597,.shtml
CONNECTIVA LINUX - TMPWATCH LOCAL DOS
Versions of the tmpwatch package as shipped with Conectiva Linux contain a
vulnerability which could lead to a local DoS. These versions, though, are not
vulnerable to the local root exploit published earlier because they do not have
the fuser option, which appeared only in later versions.
Link: http://www.net-security.org/text/bugs/971179510,7441,.shtml
SUSE LINUX - NOT AFFECTED TO TMPWATCH PROBLEM
"The tmpwatch packages as shipped with SuSE distributions are not vulnerable
to the attacks as discussed on security forums, initiated and discovered by
zenith parsec. The version of tmpwatch that we ship is a bit older than the
bleeding edge, but it has proven to do what it says, which is just as important.
We did not (silently) fix the problems in the package - the version that we use
does not have the features that cause the security problems."
Link: http://www.net-security.org/text/bugs/971179586,22555,.shtml
TRUSTIX SECURE LINUX - TMPWATCH PROBLEMS
All versions of Trustix Secure Linux have hitherto been shipped with a version
of tmpwatch that can be tricked into excessive fork()ing filling up the process
table, requiring the box to be rebooted. The version of tmpwatch can also, in
certain cases, be tricked into giving local users a root shell.
Link: http://www.net-security.org/text/bugs/971179653,98073,.shtml
EXTROPIA WEBSTORE DIR TRAVERSAL VULNERABILITY
The Web Store is a shopping cart product by eXtropia. This script merges
Selena Sol's Electronic Outlet HTML and Database shopping cart apps and
adds all new routines for error handling, order processing, encrypted mailing,
frames, Javascript and VBscript.
Link: http://www.net-security.org/text/bugs/971179782,82714,.shtml
INTERACTIVE'S WEB SHOPPER DIR TRAVERSAL VULNERABILITY
shopper.cgi allows users to switch between product pages using the
$VALUES{'newpage'} variable. This would make
http://example.com/cgi-bin/shopper.cgi?newpage=product1.htm display product1.htm.
Although this script has regex statements that single out the double dot (..),
it does not perform these checks by default.
Link: http://www.net-security.org/text/bugs/971179934,13930,.shtml
MICROSOFT SECURITY - "SHARE LEVEL PASSWORD" PATCH
Microsoft has released a patch that eliminates a security vulnerability in
Microsoft Windows 95, 98, 98SE, and Windows Me. The vulnerability could
allow a malicious user to programmatically access a Windows 9x/ME file
share without knowing the entire password assigned to that share.
Link: http://www.net-security.org/text/bugs/971265164,93554,.shtml
MANDRAKE LINUX - OPENSSH UPDATE
A problem exists with openssh's scp program. If a user uses scp to move
files from a server that has been compromised, the operation can be used
to replace arbitrary files on the user's system. The problem is made more
serious by setuid versions of ssh which allow overwriting any file on the
local user's system.
Link: http://www.net-security.org/text/bugs/971265294,96285,.shtml
SHRED 1.0 BUG REPORT
Ran a test with Shred v1.0 and found some unexpected results. This utility is
supposed to overwrite a file with several passes of different bit patterns followed
by one random pattern. The file is then unlinked. This is supposed to make the
file unrecoverable with utilities which read raw disk blocks. Using the icat utility
from Dan Farmer and Wietze Venema's TCT Toolkit it appears that the data is
not overwritten. This test was done on two different RedHat 6.0 systems.
Link: http://www.net-security.org/text/bugs/971265364,54158,.shtml
HP JETDIRECT MULTIPLE DOS
The firmware in the HP JetDirect card contain multiple vulnerabilities that can
have effects ranging from the service crashing to the printer initiating a
firmware upgrade based on random garbage in the memory, and in the last
case powercycling won't fix the crash. It requires a new firmware burn by
eg. HP to restore the Jetdirect card.
Link: http://www.net-security.org/text/bugs/971265417,19017,.shtml
MS - WEBTV FOR WINDOWS DENIAL OF SERVICE
There is a denial of service vulnerability in WebTV for Windows that may allow
a malicious user to remotely crash either the WebTV for Windows application
and/or the computer system running WebTV for Windows. Restarting the
application and/or system will return the system to its normal state. Microsoft
has released a patch that eliminates this security vulnerability.
Link: http://www.net-security.org/text/bugs/971375310,5567,.shtml
MANDRAKE LINUX - APACHE UPDATE
The Apache web server comes with a module called mod_rewrite which is used
to rewrite URLs presented by the client prior to further processing. There is a
flaw in the mod_rewrite logic that allows an attacker to view arbitrary files on
the server system if they contain regular expression references.
Link: http://www.net-security.org/text/bugs/971375814,81283,.shtml
PHP REMOTE FORMAT STRING VULNERABILITIES
Format string vulnerabilities exist in the error logging routines of PHP versions 3
and 4, allowing remote users to execute arbitrary code under the web server's
user id. A web server having PHP installed and one or more PHP scripts is
vulnerable to the problem if error logging is enabled in php.ini. Also any PHP
script using the "syslog" command of PHP may be vulnerable, regardless of
error logging.
Link: http://www.net-security.org/text/bugs/971375894,65809,.shtml
PROBLEM WITH NETSCAPE MESSAGING SERVER 4.15
The problem is that the POP3 server displays a different message for an
authentication error due to an invalid password then for one due to an invalid
username. This could be used to "harvest" email addresses for spam lists.
Link: http://www.net-security.org/text/bugs/971439529,51461,.shtml
APACHE 1.3.14 RELEASED
The Apache Software Foundation and The Apache Server Project are pleased
to announce the release of version 1.3.14 of the Apache HTTP server. Version
1.3.13 was never released. This version of Apache is primarily a security fix and
bug fix release, but there are a few new features and improvements.
Link: http://www.net-security.org/text/bugs/971484402,83017,.shtml
DEBIAN LINUX - CURL AND CURL-SSL UPDATE
The version of curl as distributed with Debian GNU/Linux 2.2 had a bug in the
error logging code: when it created an error message it failed to check the size
of the buffer allocated for storing the message. This could be exploited by the
remote machine by returning an invalid response to a request from curl which
overflows the error buffer and trick curl into executing arbitrary code.
Link: http://www.net-security.org/text/bugs/971559341,76634,.shtml
REMOTE RETRIEVAL OF AUTHENTICATION DATA FROM IE
"We will show that it could be possible to retrieve the cached authentication
data from your user's web browser with little or no user's cooperation, even
when due care was taken to protect the communication between browser
and server with SSL."
Link: http://www.net-security.org/text/bugs/971559586,2881,.shtml
MS - "CACHED WEB CREDENTIALS" VULNERABILITY
Microsoft has released a patch that eliminates a security vulnerability in
Microsoft Internet Explorer. Under a daunting set of conditions, the
vulnerability could enable a malicious user to obtain another user's userid
and password to a web site.
Link: http://www.net-security.org/text/bugs/971559684,92219,.shtml
MANDRAKE LINUX - MOD_PHP3 UPDATE
PHP version 3 which ships with Linux-Mandrake are vulnerable to format string
attacks due to logging functions that make improper use of the syslog() and
vsnprintf() functions. This renders PHP3-enabled servers vulnerable to
compromise by remote attackers. This attack is only effective on PHP
installations that log errors and warnings while those servers that do
not are not affected. By default, Linux-Mandrake systems do not have
logging enabled.
Link: http://www.net-security.org/text/bugs/971559791,26568,.shtml
ANACONDA FOUNDATION DIRECTORY VULNERABILITY
Synnergy Labs has found a flaw within Anaconda Foundation Directory that
allows a user to successfully traverse the filesystem on a remote host,
allowing arbitary files/folders to be read
Link: http://www.net-security.org/text/bugs/971559891,18741,.shtml
CALDERA SECURITY UPDATE: FORMAT BUG IN PHP
There's a format bug in the logging code of the mod_php3 module. It uses
apache's aplog_error function, passing user-specified input as the format
string. This can be exploited by a remote attacker to execute arbitrary shell
commands under the HTTP server account (user httpd). In order for this bug
to be exploitable, the PHP error logging must be enabled. By default, error
logging is off.
Link: http://www.net-security.org/text/bugs/971690142,53185,.shtml
WINU 1.0-5.1 BACKDOOR PASSWORDS
"After downloading WinU 5.1 I noticed the built-in "emergency password"
capability, mentioned in the help file. I decided to take a look around.
AND WOW! GOT 'EM ALL!"
Link: http://www.net-security.org/text/bugs/971690328,13624,.shtml
DEBIAN LINUX - LOCAL EXPLOIT IN NIS PACKAGE
The version of nis as distributed in Debian GNU/Linux 2.1 and 2.2 contains an
ypbind package with a security problem. ypbind is used to request information
from a nis server which is then used by the local machine. The logging code in
ypbind was vulnerable to a printf formating attack which can be exploited by
passing ypbind a carefully crafted request. This way ypbind can be made to
run arbitrary code as root.
Link: http://www.net-security.org/text/bugs/971690367,54647,.shtml
MS - "NETMEETING DESKTOP SHARING" VULNERABILITY
Microsoft has released a patch that eliminates a security vulnerability in
NetMeeting, an application that ships with Microsoft Windows 2000 and is
also available as a separate download for Windows NT 4.0. The vulnerability
could allow a malicious user to temporarily prevent an affected machine from
providing any NetMeeting services and possibly consume 100% CPU utilization
during an attack.

UNVERIFIED FIELDS - A PROBLEM WITH FIREWALLS & FIREWALL TECHNOLOGY TODAY
by Ofir Arkin
The following problem (as discussed in this paper) has not yet been identified.
Certain firewalls today, will not authenticate the validity of certain protocol fields,
within the packet they are processing. The risk is exposure of information. What
kind of information can be exposed? Mainly it will be unique patterns of behavior
produced by the probed machines answering our crafted queries (or other kind of
network traffic initiated in order to elicit a reply). Those patterns will help a
malicious computer attacker to identify the operating systems in use.

TESTING TIMES FOR TROJANS by Ian Whalley
In the field of computing, Trojan horses have been around for even longer
than computer viruses � but traditionally have been less of a cause for
concern amongst the community of PC users. In recent years, however,
they have been the focus of increased attention from anti-virus companies
and heightened levels of user concern. This paper aims to investigate the
Trojan phenomenon; particular attention will be paid to the claims made in
the field of NVM detection and those made by those who aim to test the
vendors� claims.

with the virus spreading has occurred another syndrome, which is not any less
dangerous � virus hoaxes.

THINK UNIX
The many variants of the Unix operating system require use of a mode of
thought that's significantly different from the one that's required by simpler
operating systems. Think Unix introduces readers to important fundamental
and intermediate Unix commands and, in the process, inculcates them in the
Unix way of thinking. It's a worthy goal in a world with more Linux users than
ever, and author Jon Lasser accomplishes it. He's both a capable writer and a
knowledgeable user of Unix shell commands. Lasser uses bash under Red Hat
Linux in most examples, which usually apply equally well to other Unix variants,
and makes asides about other shells and environments, as needed.

SOLARIS 8: THE COMPLETE REFERENCE
This book shows you what you need to understand if you want to make a
living as administrator of a modern Sun workstation. Of course, this book is
not absolutely complete - no technical book about a subject as large as
Solaris 8 could hope to be - but it should be more than adequate for most
readers' purposes. Whether you have experience with another enterprise
operating system and have recently been charged with figuring out Solaris,
or you're a long-time Solaris jock and need a handy reference to guide you
through procedures that you don't follow every day, this book has your
number.

THE HUNDREDTH WINDOW: PROTECTING YOUR PRIVACY AND SECURITY IN
THE AGE OF THE INTERNET
The proverbial hundredth window represents the most vulnerable link in a system.
It derives from an allegory relating castle windows to potential security holes. If
even one out of a hundred windows is left open, security becomes compromised.
Since the Internet maximizes information sharing (admittedly a largely beneficial
enterprise) would-be big-time marketers and shady characters can - without
trying all that hard--spy on your Web clicking habits, read your e-mail, and even
see files on your hard disk drive. This means you may receive spam from
marketers who think they know what kind of stuff you like to buy--e-mail that
can be helpful to some and aggravating to others. Sharing your name and other
identifying personal information can cause you more serious problems: someone
else could use that information to commit fraud or other crimes--and you would
be responsible.

WINDOWS: SYSTEM POLICY EDITOR
Considering that most administrators could figure out the System Policy Editor
through experimentation and some study of its documentation - this book
includes lots of advice on proper use of the utility. Case studies are most
helpful; a typical one explains how to set up system policies for a machine
that will live in a university computer lab that's accessible to the public.
Topics covered: How and why to use the Windows System Policy Editor to
set user, group, and computer access privileges on computers that run
Windows 9x and Windows NT. The user interface is fully documented, as
are the structure and syntax of policy files and templates.
