Linux Advisory Watch is a comprehensive newsletter that outlines the
security vulnerabilitiaes that have been announced throughout the week.
It includes pointers to updated packages and descriptions of each
vulnerability.
This week, advisories were released for kdeutils, noffle, dhcp3, tomcat3,
courier, mysql, fetchmail, vim, webalizer, postgresql, and cvs. The
distributors include Debian, Guardian Digital's EnGarde Secure Linux,
Mandrake, and Yellow Dog.
ENCRYPTION + AUTHENTICATION = TRUST
You may think people will regard your business as trustworthy because
you.ve got a 128-bit encryption certificate, but encryption does not
guarantee trust. Thawte believes in rigorous authentication - Download

Patching It Up - Patching and upgrading software requires more than
running a few commands. Having a patch recovery plan, communicating with
developers on that server, and knowing who to contact in case of a botched
patch job is critical.

LINUXSECURITY.COM FEATURE: Newest Members of the Team Just to give
everyone an idea about who writes these articles and feature stories that
we spend so much of our time reading each day, I have decided to ask Brian
Hatch and Duane Dunston, the newest members of the LinuxSecurity.com team,
a few questions.

+---------------------------------+
| Package: kdeutils | ----------------------------//
| Date: 01-24-2003 |
+---------------------------------+
Description:
The KDE team discovered several vulnerabilities in the K Desktop
Environment. In some instances KDE fails to properly quote parameters of
instructions passed to a command shell for execution. These parameters may
incorporate data such as URLs, filenames and e-mail addresses, and this
data may be provided remotely to a victim in an e-mail, a webpage or files
on a network filesystem or other untrusted source.

| Package: noffle | ----------------------------//
| Date: 01-27-2003 |
+---------------------------------+
Description:
Dan Jacobson noticed a problem in noffle, an offline news server, that
leads to a segmentation fault. It is not yet clear whether this problem
is exploitable. However, if it is, a remote attacker could trigger
arbitrary code execution under the user that calls noffle, probably news.

Description:
Florian Lohoff discovered a bug in the dhcrelay causing it to send a
continuing packet storm towards the configured DHCP server(s) in case of a
malicious BOOTP packet, such as sent from buggy Cisco switches.

| Date: 01-28-2003 |
+---------------------------------+
Description:
A maliciously crafted request could return a directory listing even when
an index.html, index.jsp, or other welcome file is present. File contents
can be returned as well.

| Package: courier | ----------------------------//
| Date: 01-30-2003 |
+---------------------------------+
Description:
The developers of courier, an integrated user side mail server, discovered
a problem in the PostgreSQL auth module. Not all potentially malicious
characters were sanitized before the username was passed to the PostgreSQL
engine. An attacker could inject arbitrary SQL commands and queries
exploiting this vulnerability. The MySQL auth module is not affected.

| Package: fetchmail | ----------------------------//
| Date: 01-27-2003 |
+---------------------------------+
Description:
Stefan Esser of e-matters, while re-auditing the Fetchmail package, found
another vulnerability. This heap overflow vulnerability allows a
malicious remote attacker to crash Fetchmail or potentially execute
arbitrary code as the user under which Fetchmail is being run.

| Package: vim | ----------------------------//
| Date: 01-27-2003 |
+---------------------------------+
Description:
VIM allows a user to set the modeline differently for each edited text
file by placing special comments in the files. Georgi Guninski found that
these comments can be carefully crafted in order to call external
programs. This could allow an attacker to create a text file such that
when it is opened arbitrary commands are executed.

| Date: 01-27-2003 |
+---------------------------------+
Description:
A buffer overflow in Webalizer versions prior to 2.01-10, when configured
to use reverse DNS lookups, may allow remote attackers to execute
arbitrary code by connecting to the monitored Web server from an IP
address that resolves to a long hostname.
