----------------------------------------------------------------------
Due to the recent barrage of e-mails we've received, I once again would
like to give my periodic explanation of how Security Alert Consensus
(SAC) works.
First off, SAC is an unbiased publication -- we report on as many
plausible security vulnerabilities as we can get our hands on. Due to
those fun things known as 'deadlines,' all vulnerabilities released
during a Wednesday through the following Tuesday period are compiled
into one issue. That means issues that come out Wednesday or early
Thursday will not appear in that immediate Thursday's issue, but rather
the following Thursday's issue. This was witnessed with the recent
Microsoft/VeriSign certificate issue.
SAC is a category-centric publication, meaning that you can pick which
categories of information you wish to receive. This allows you to
minimize the content of your newsletter and personalize it according to
your interests. But this personalization can be a double-edged sword:
If you do it incorrectly -- that is, you do not subscribe to the right
categories -- you may miss information you want. Once again, I would
like to draw everyone's attention to the 'Cross-Platform' category. Many
vulnerabilities fall under this heading, and odds are it will contain
items of interest (at times) to just about any administrator.
Many people also are concerned about the fact that we lack specific
categories for particular platforms, which results in us not reporting
issues for that platform. This is why we have the wonderful catch-all
category of 'Other.' If the vulnerability doesn't naturally fall into
'Cross-Platform' and we have no specific category to place it in, it
will be found in 'Other.' However, we are evaluating the addition of
more categories for future issues.
Don't worry if you haven't picked the correct category selections.
Instructions on changing your category selections are included at the
end of this and every other SAC newsletter. You also can catch missed
items by viewing the archived versions of the newsletter, which contain
every item. They are viewable at:

*** {01.16.032} Linux - IPTables FTP RELATED connections bypass filters
A vulnerability in the ip_conntrack_ftp module, which is responsible
for tracking incoming FTP connections, has been found. This
vulnerability could be used to bypass IPTables firewall rules if
IPTables is configured to allow RELATED connections to pass unhindered,

can trick the ip_conntrack_ftp module into creating RELATED connections,
thus allowing various outbound connections to the network of the
firewall itself.

A report was released recently concerning the Lightwave ConsoleServer

listening on port 5000, he or she can obtain a list of currently
logged-in users without any authentication information. The list of
obtained users then can be used in a brute-force attack to the telnet
service. The telnet service neither limits, logs nor imposes any
repercussions on invalid login attempts.
