Red Hat Linux update for Linux Slapper worm

Red Hat Linux update for Linux Slapper worm

am 20.09.2002 12:07:18 von John.Airey

You can disregard the following email if you don't use Red Hat Linux 7.0 and
above.

Having waited for an update to openssl from RedHat, I decided to call them.
They've not had anyone ask them for an update, which came as a bit of a
shock. I have therefore registered a request to release an update to openssl
via their bugzilla site. For information, the vulnerability that Linux
Slapper takes advantage of was fixed in openssl on 30th July. See
http://www.cert.org/advisories/CA-2002-23.html for details.

The previous openssl errata at
http://rhn.redhat.com/errata/RHSA-2002-160.html has no mention of the buffer
overflows fixed on July 30th. This package was built on August 1st, so it is
unlikely to include the 0.9.6d patches due to the time lag of testing
patches by Red Hat.

You can add your comments to the bug report at
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=74312. If I haven't
heard from them soon, I will probably release an update myself.

I cannot give you a definite statement about what I don't know, but I can
participate in speculating :-)
Redhat as well as other system builders have been informed well in advance
about the vulnerabilities including patches to fix them, such that tests
could be performed and updates be prepared. It was our intention that
updated binary packages could be made available more or less in parallel
to our announcement and source code release.

That does not mean, that the fix is actually in. I simply don't know.

Best regard,
Lutz
PS. OpenSSl team member Mark Cox is actually working for Redhat...

So why do your telephone support people not know about this? They advised me
to log it on bugzilla in the first place. Why isn't this page linked to from
your errata site? That's where people look for updates. Why no information
to CERT or Bugtraq?

You're beginning to make Microsoft look professional, which is a scary
thought.

On the www.redhat.com home page you will find a link about the slapper
worm, http://www.redhat.com/support/alerts/linux_slapper_worm.html

Versions of OpenSSL that are not vulnerable to this worm have been
available from Red Hat since 29th July 2002. Customers who have kept their
systems up to date are not impacted by this worm.

http://rhn.redhat.com/errata/RHSA-2002-155.html was released on the 29th
of July and fixed the vulnerability that the Linux Slapper worm takes
advantage of. We released a new version of OpenSSL a little later that
fixed one of the other vulnerabilities,
http://rhn.redhat.com/errata/RHSA-2002-160.html

If you upgraded to either of the OpenSSL errata and followed the
instructions about restarting your services you are protected against the
Linux slapper worm.

Thanks, Mark
