RE: Patch management tool

Patrick is right, Red Hat will patch services but doesn't change the
default version number in their banners. That way, you don't really know
what level a service is, if you are trying to attack it.

I did a "rpm -q OpenSSH" and it came back with a older version. Maybe it
was patched and I couldn't tell..it is possible. But I know for sure I
running the newest now. =)

I can't remember the term for this process (patching without changing
the presented version) but I do know that RH does it. This is a cool
trick but in my mind it doesn't protect you very much. If you see a old
verison, a person will try all older attacks. Making them waste their
time and maybe leaving a trace? Maybe.

Redhat has always had a habit of patching the vulnerability not the
version. While it shows an older version it could be patched.

My FC2 system says

[rootxxx root]# telnet localhost 22
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
SSH-1.99-OpenSSH_3.6.1p2

But if you go to:
http://download.fedora.redhat.com/pub/fedora/linux/core/updates/2/i386/

Or check here for any advisories
http://secunia.com/search/?search=fedora+ssh&w=0

There is no update for SSH. You need to try the actual exploit against
the box to see if it is really vulnerable, for redhat/fedora systems an
old rev number does not mean an exploitable system

Yum works really well, but it shouldn't be your only tool to check for
updates. Yum only works with special list of rpm updates.

I use Yum on my FC2 box. I modified my yum.conf to use all the mirrors
and everything. After doing a Nessus scan on my own box, I saw that my
SSH verion was pre-3.7.1

Not good, yum didn't see it and I had to update my OpenSSH myself.

Yum is good, but keeping up with software versions, knowing what is
installed on your box and what is running, and watching vuln news is one
of the best ways.

I know this isn't the place for his question, but it isn't totally OT.
Vuln scanning your computer with Nessus and other tools can help you
find programs that need patches.

Everyone on this list knows that you should test what will be used
against you. The essence of Pen-Testing.

As mentioned by another on this list, this isn't really the appropriate
list for such an inquiry, however, not to leave you without an answer,
for any linux distro that uses rpm's, yum - Yellow dog Updater, Modified
would fit the need. It's used extensively and is relatively straight
forward in implementation. You can find it here:

http://linux.duke.edu/projects/yum/

In the future, the focus-linuxsecurityfocus.com would be a better place
for a linux related inquiry.
