About the W32/Blaster worm: Yeah, it was painful, but it could have been
worse. That is, unless you allow arbitrary TFTP traffic to pass through
your network and gateways.

Come on folks, this is not a well-written worm. Its method of scanning
for new hosts is slow and not as effective as it could be. It requires
not only port 135 access but also port 69 (TFTP) access. Just imagine
if the worm pulled everything in over the established connection (rather
than using TFTP) and it was more efficient at scanning. If you think
the current incarnation was a nightmare....

One common situation popped up often enough that we feel it important
to comment. Many folks locked down their gateways and checked their
perimeter servers for vulnerability. Satisfied that nothing could come
in from the Internet, they were humbled when an internal employee
brought in an infected laptop from home. Sure, the servers were OK, but
the desktops proved to be a fertile worm incubation playground.

Moral to the story: Security doesn't stop at the perimeter. From the
mightiest of servers to the lowliest of desktops, and all print servers
in-between, everything needs to be patched when dealing with a
nondiscriminatory worm.

*** {03.32.006} Win - 121 WAM! Server FTP root escaping

http://archives.neohapsis.com/archives/vulnwatch/2003-q3/0071.html

*** {03.32.008} Win - Meteor FTP server USER overflow

Meteor FTP server version 1.5 contains a buffer overflow in the handling
of a large FTP USER command. Execution of arbitrary code may be
possible.

This vulnerability is not confirmed.

Source: SecurityFocus Bugtraq
http://archives.neohapsis.com/archives/bugtraq/2003-08/0092.html

*** {03.32.010} Win - MDaemon auth allows blank password

Source: Red Hat
http://archives.neohapsis.com/archives/linux/redhat/2003-q3/0018.html

*** {03.32.012} Linux - xpcd-svga HOME env var overflow

*** {03.32.002} BSD - FreeBSD invalid signal values

A FreeBSD advisory indicates the ptrace() subsystem, as well as the
spigot device driver, can allow a local attacker to send
invalid/negative signals to applications, potentially causing a denial
of service or an integer comparison vulnerability.

FreeBSD branches as of Aug. 10, 2003, contain the fix.

Source: FreeBSD
http://archives.neohapsis.com/archives/freebsd/2003-08/0101.html

*** {03.32.007} BSD - FreeBSD ibcs2 statfs() exposes kernel memory

A FreeBSD advisory indicates the ibcs2 support, when enabled, can allow
a local attacker to read portions of the kernel memory because of a bug
in the statfs() translation function.

FreeBSD branches as of Aug. 10, 2003, contain the fix.

Source: FreeBSD
http://archives.neohapsis.com/archives/freebsd/2003-08/0102.html

*** {03.32.011} Cross - pam-pgsql user name format string vuln

The pam-pgsql PAM authentication module is vulnerable to a format string
attack, thereby allowing an attacker to execute arbitrary code.

This vulnerability is confirmed. Updated Debian DEBs are listed at the
reference URL below.

Source: Debian
http://archives.neohapsis.com/archives/linux/debian/2003-q3/0246.html

*** {03.32.013} Cross - SBM protocol hijacking via RSVP

A released research paper discusses the possibility of using higher
priority RSVP packets to preempt any current RSVP servers, thus allowing
a rouge RSVP server to start handling requests.

This is an unconfirmed, general protocol attack that may or may not
affect any actual products. One solution is to ensure your RSVP servers
use the maximum priority value (255).

Source: SecurityFocus Bugtraq
http://archives.neohapsis.com/archives/bugtraq/2003-08/0114.html

*** {03.32.015} Cross - Netris malicious server overflow

system when connecting.

This vulnerability is not confirmed.

Source: SecurityFocus Bugtraq
http://archives.neohapsis.com/archives/bugtraq/2003-08/0127.html

*** {03.32.016} Cross - iPlanet Directory Server admin server file
                access

The administration service included with iPlanet Directory Server
version 5.1 allows anyone with admin access to use the admin HTTP
service to read arbitrary files on the system.

The advisory indicates confirmation by the vendor, which released Sun
Directory Server version 5.2 and iPlanet Directory Server 5.1 Service
Pack 2.

Source: SecurityFocus Bugtraq
http://archives.neohapsis.com/archives/bugtraq/2003-08/0078.html

- --- Mac OS News --------------------------------------------------------

*** {03.32.018} MacOS - IPNetMonitorX/IPNetSentryX utility script vulns

The IPNetMonitorX and IPNetSentryX application suites come with various
helper utilities that are installed setuid root. These utilities allow
arbitrary local attackers to sniff the network and possibly execute
arbitrary code with elevated privileges because of a format string bug
in tcpflow.

The advisory indicates vendor confirmation.
