investigation is undertaken and results are presented. The article
provides an opportunity to follow the trail of incident response for the
real case.

| php | ----------------------------//
+---------------------------------+
Several flaws have been found in the way PHP handles multipart/form-data
POST requests. Each of the flaws could allow an attacker to execute
arbitrary code on the victim's system.
Caldera:
ftp://ftp.caldera.com/pub/updates/OpenLinux/3.1.1/Server/current/RPMS
php-4.0.6-3.2.i386.rpm
1bbbc55e7dfd717f02b3668c57891edf
php-doc-4.0.6-3.2.i386.rpm

Caldera Vendor Advisory:

+---------------------------------+
| fetchmail | ----------------------------//
+---------------------------------+
When retrieving mail from an IMAP server, the fetchmail e-mail client will
allocate an array to store the sizes of the messages which it will attempt
to fetch. The size of the array is determined by the number of messages
that the server claims to have. Unpatched versions of fetchmail prior to
5.9.10 did not check whether the number of e-mails the server claimed was
too high, allowing a malicious server to cause the fetchmail process to
write data outside of the array bounds.
Red Hat Linux 7.3 i386:
ftp://updates.redhat.com/7.3/en/os/i386/
fetchmail-5.9.0-11.i386.rpm
8ac6d5614b18de67e5dd53ea8de64e16
ftp://updates.redhat.com/7.3/en/os/i386/
fetchmailconf-5.9.0-11.i386.rpm
51eeebc63b4e44bbf9de2d3ba3d408ff
Red Hat Vendor Advisory:
http://www.linuxsecurity.com/advisories/redhat_advisory-2080.html
+---------------------------------+
| webmin | ----------------------------//
+---------------------------------+
A vulnerability exists in all versions of Webmin prior to 0.970 that
allows a remote attacker to login to Webmin as any user. All users of
Webmin are encouraged to upgrade immediately.
Mandrake Linux 8.2:8.2
http://www.mandrakesecure.net/en/ftp.php
/RPMS/webmin-0.970-1.1mdk.noarch.rpm
00b798a4d1d59c53d644809846e9980b
Mandrake Vendor Advisory:
http://www.linuxsecurity.com/advisories/mandrake_advisory-2081.html
+---------------------------------+
| dhcp | ----------------------------//
+---------------------------------+
A remote exploitable format string vulnerability was found in the logging
routines of the dynamic DNS code of dhcpd. This vulnerability allows an
attacker, usually within the LAN served by the DHCP server, to get remote
root access to the host running dhcpd.
i386 Intel Platform: SuSE-8.0
ftp://ftp.suse.com/pub/suse/i386/update/8.0/n2/
dhcp-server-3.0.1rc6-8.i386.rpm
