Today's focus: New sniffer tool for Win 2K/XP

By Jason Meserve

A new packet sniffer tool is available for Windows 2000 and XP
users. NGSSniff uses the RAW_SOCKETs capability on the two
operating systems to run, meaning users do not have to install
any special drivers to use the program. Users can analyze
captured packets while the sniffer is running.

NGSSoftware offers the NGSSniff program free of charge at:
http://www.nextgenss.com/products/ngssniff.html


Today's bug patches and security alerts:


* Caldera patches vulnerability in wu-ftpd

A flaw in wu-ftpd's ftpglob() function could be exploited to
gain root access on the affected server. Caldera OpenServer
users can download a fix for the problem at:
ftp://stage.caldera.com/pub/security/openserver/CSSA-2002-SCO.1/


* Caldera patches IMP/HORDE

A cross-scripting vulnerability has been found in IMP/HORDE
that could allow attackers to send an e-mail message with a
malformed URL. This malicious URL could be used to open the
current mail session to attackers, allowing them to read and
delete e-mail on the affected machine. Caldera OpenLinux 3.1
Server users can download an update from:
ftp://ftp.caldera.com/pub/updates/OpenLinux/3.1/Server/current/RPMS


* Bug in PGP 7.0 Outlook plug-in

A flaw in the way the PGP 7.0 Outlook plug-in handles certain
messages can leave those encrypted messages saved as clear
text. PGP 7.1 offers a fix for the flaw:
http://www.pgp.com/naicommon/download/upgrade/upgrades-patch.asp


* Vulnerability found in Slash code

A flaw has been discovered in Slash, the code that runs
Slashdot and other similar sites. The flaw could allow any
logged-in user to log in as any other user. This could be
exploited to take control of the affected site, including
posting information to the site. Users should upgrade to Slash
2.2.3. For more, go to:
http://sourceforge.net/project/showfiles.php?group_id=4421&release_id=68516



* Linux-Mandrake updates glibc

A flaw in the glob() function in the glibc library could be
used to exploit programs that pass information through the
function. A malicious user could modify information being
passed through the function. For more, go to:
http://www.linux-mandrake.com/en/security/2001/MDKSA-2001-095-1.php3


Today's roundup of virus alerts:


* JS.Gigger.A.Worm - Another worm that spreads via Outlook and
network-attached drives. This one arrives with the subject line
"Outlook Express Update," a body text of "MSNSofware Co." and
an attachment called "mmsn_offline.htm." It also attempts to
delete files on the infected C: drive. (Computer Associates,
Sophos)

* Troj/Palukka - A Trojan Horse that allows a malicious user to
control the infected machine via IRC channels. (Sophos)

* VBS/RTF-Senecs - This virus arrives in an e-mail titled
"Scene from last weekend," with body text reading "Please do
not forward" and an attachment called "scenes.zip." The
compressed attachment contain two files that when opened,
spread the virus and drop a Trojan horse on the infected
machine. (Sophos)

* Troj/Optix-03-C - A Trojan horse that acts a server for
malicious users to gain access to the infected machine. This
file is dropped by VBS/RTF-Senecs. (Sophos)

* Troj/WebDL-E - Another piece of the VBS/RTF-Senecs puzzle.
This Trojan horse drops the Troj/Sub7-21-I Backdoor onto the
infected machine and sends out an alert via an ICQ account.
(Sophos)

* Troj/Sub7-21-I - Used by hackers as a backdoor into infected
systems, this Trojan can be used to acquire sensitive
information about the infected machine, including user
passwords. (Sophos)

* W32/Lohack-A - An e-mail mass-mailer that comes with the
subject of "Hacking course..." and an attachment called
"hacking.exe." It looks for e-mail addresses stored on the
infected machine in various file types. (Sophos)


>From the interesting reading department:

* Wireless insecurities

It's a sight that would make any sales manager proud: your
company's top sales rep is dutifully e-mailing detailed reports
on the day's activities over a public wireless 802.11b network
as he waits for his lunch across the street from the office.
But would your sales manager be quite so happy if she knew the
sensitive data transmissions sent from the rep's laptop could
be grabbed by anyone else within a few hundred yards?

* Secure Computing offers firewall appliance

Secure Computing Thursday introduced its first firewall
appliance based on Sidewinder 5.2, previously sold only as

enterprise customers.
