Vulnerabilities Title: MySQL security flaws uncovered
Source: ZDNet
Date Written: December 16, 2002
Date Collected: December 16, 2002
Security vulnerabilities were discovered in the MySQL database system
that could create a denial of service problem or allow an attacker to
"bypass the MySQL password check or to execute arbitrary code." The
vulnerabilities are rated "Medium to Critical," and other vulnerabilities
were discovered in the MySQL client libraries. The flaws affect all versions
of the database prior to 3.23.53a and 4.0.5a. The company that discovered
the vulnerabilities will not publish the exploit. The MySQL database system
is "commonly used in Linux environments but which runs also on Microsoft
platforms, HP-Unix, Mac OS and more." An updated "version 3" (3.23.54) has
been released and is immune to the flaws.

Malware Title: New 'Iraq Oil' Network Worm Found
Source: InfoWorld
Date Written: December 18, 2002
Date Collected: December 18, 2002
A new worm was detected called W32/Lioten (Net-Oil backwards), or the
names Iraq_oil, Datrix, W32.Lioten, or I-Worm.Lioten and affects Windows
2000 and Windows XP machines that share folders with others and do not have
firewall protection. "Lioten scans the Internet for vulnerable Windows
machines that are sharing folders with other users on a home or business
network. The worm finds new hosts to infect by randomly generating and
attempting to connect to IP (Internet Protocol) addresses on the Internet.
The worm listens for responses on port 445 from machines using Windows
Server Message Block (SMB), a file and resource sharing protocol used in
Windows environments." The Internet Storm Center noted an increase in port
445 scans. If the worm receives a response from the server, it will launch a
brute force attack. "The worm first obtains a list of user accounts on the
machine and then attempts to log in to each of those accounts by supplying
values from its own list of li kely passwords such as 'admin,' 'root,'
'1234' and 'asdf'." The worm will install a copy of itself, iraq_oil.exe, in
the System32 directory if it is successful in logging in. Leading anti-virus
vendors have given the worm a low rating because the worm has not spread
widely.

Vulnerabilities
Title: CERT® Advisory CA-2002-36 Multiple Vulnerabilities in SSH
Implementations
Source: CERT
Date Written: December 16, 2002
Date Collected: December 18, 2002
The CERT Coordination Center of Carnegie Mellon University issued an
advisory warning that "Multiple vendors' implementations of the secure shell
(SSH) transport layer protocol contain vulnerabilities that could allow a
remote attacker to execute arbitrary code with the privileges of the SSH
process or cause a denial of service. The vulnerabilities affect SSH clients
and servers, and they occur before user authentication takes place."
Exploitation of this vulnerability could allow an attacker to execute
arbitrary code or cause a denial of service. The vulnerabilities affect "Secure
shell (SSH) protocol implementations in SSH clients and servers from
multiple vendors," users should upgrade or apply a patch, according to their
specific vendor. OpenSSH is not vulnerable.

Security firm eEye Digital Security is reporting a flaw "in Macromedia's
animation software [that] leaves web surfers vulnerable to attack when they
visit an internet site or, even open an email." With a hand-edited
Macromedia Flash, or SWF, file, an attacker "can compromise a PC or
Macintosh if its user views the file with the Shockwave Flash Player plug-in
for Internet Explorer, Netscape or other browsers." Macromedia reports that
more than 90 percent of Web browsers have installed Flash software. Users
are urged to upgrade immediately.

Malware Title: E-card virus warning for Christmas
Source: CNN
Date Written: December 19, 2002
Date Collected: December 20, 2002
Beware the Christmas e-card! Sophisticated computer viruses might be
hiding behind some of the holiday e-cards this season, analysts warn. While
many e-cards sites are legitimate, some online Christmas cards are "smoke
screens" for viruses and worms. "First they will remove your anti-virus
program so that you do not know they are there, then they do all sorts of
nasty things like mailing out your address book so that your friends will be
affected," says Alex Shipp of Message Labs. The fakes look legitimate, so it
is especially important to be vigilant.

Vulnerabilities Title: Security flaw threatens Cisco Web site
Source: ZDNet
Date Written: December 29, 2002
Date Collected: December 20, 2002
Securiteam, an online security portal, have found a "session theft"
vulnerability on the Cisco Web site. The vulnerability would allow attackers
to "cause users to view third-party malicious JavaScript or HTML code as if
it were the legitimate content offered by Cisco," the advisory said. XSS
vulnerabilities have become quite "in vogue" lately, with many security
researchers focusing their efforts in detection and elimination of the
security problem. The recently held hacking competition, OpenHack IV, dished
out US$500 to a single entrant, Jeremy Poteet, who found XSS vulnerabilities
in the application being tested, which was engineered by Oracle.
