Re: Re: [RHSA-2003:279-01] Updated OpenSSH packages fix potential vulnerability

OpenSSH runs on a number of platforms, Windows included.  To say this
reflects on GNU/Linux or any Linux distro is just nonsense.

On Tue, 16 Sep 2003 11:29:30 -0700 Dave Monk <dave () themaneater com> wrote:
Recent security advisories featuring the operating system known as
'GNU/Linux' (formerly minix) has had a negative effect on the
listserv.

The problem stems from the polymorphic, virus-like phenomenon also
known as the 'Linux distro', the Linux distro allows any single
permutation of a base Linux install (such as location of the mail
spool) to actually qualify and require an entire new operating
system distribution.  At this point in time there are over 50
distros out there.

The cascade failure effect is that the minute a hole or flaw in
a
base Linux subsystem such as the kernel or system tools immediately
causes a flood of 'vendor' emails sent to bugtraq describing each
way to disable/upgrade the broken feature on their OS.

The effect is that the 'signal to stupid-linux-bug ratio' on the
lists gets completely out of whack thereby diluting the utility
of the list.

Solutions:

 None. (how do you expect to stop a tidal wave of suicidal VC money?)

Workarounds:

1) All advisories should be filtered through RMS, which would achieve
  the desired effect of delaying their posting indefinitely.
2) All such advisories should be prefixed by '[YASLB]' in the subject
line
  (yet another stupid linux bug) so I can filter this stupid crap.

thanks,
everyone

                   Red Hat Security Advisory

Synopsis:          Updated OpenSSH packages fix potential vulnerability
Advisory ID:       RHSA-2003:279-01
Issue date:        2003-09-16
Updated on:        2003-09-16
Product:           Red Hat Linux
Keywords:          
Cross references:  
Obsoletes:         RHSA-2003:222
CVE Names:         CAN-2003-0693
- ------------------------------------------------------------

1. Topic:

Updated OpenSSH packages are now available that fix a bug that
may be
remotely exploitable.

2. Relevant releases/architectures:

Red Hat Linux 7.1 - i386
Red Hat Linux 7.2 - i386, ia64
Red Hat Linux 7.3 - i386
Red Hat Linux 8.0 - i386
Red Hat Linux 9 - i386

3. Problem description:

OpenSSH is a suite of network connectivity tools that can be used
to
establish encrypted connections between systems on a network and
can
provide interactive login sessions and port forwarding, among
other functions.

The OpenSSH team has announced a bug which affects the OpenSSH
buffer
handling code.  This bug has the potential of being remotely exploitable.

All users of OpenSSH should immediately apply this update which
contains a
backported fix for this issue.

4. Solution:

Before applying this update, make sure all previously released
errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. 
Only those
RPMs which are currently installed will be updated.  Those RPMs
which are
not installed but included in the list will not be updated.  Note
that you
can also use wildcards (*.rpm) if your current directory *only*
contains the
desired RPMs.

Please note that this update is also available via Red Hat Network.
Many
people find this an easier way to apply updates.  To use Red Hat
Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the
appropriate
RPMs being upgraded on your system.

If up2date fails to connect to Red Hat Network due to SSL Certificate

Errors, you need to install a version of the up2date client with
an updated 
certificate.  The latest version of up2date is available from
the Red Hat 
FTP site and may also be downloaded directly from the RHN website:

https://rhn.redhat.com/help/latest-up2date.pxt
