Fedora Legacy Update Advisory

Synopsis: Updated openssh packages fix security issues
Advisory ID: FLSA:168935
Issue date: 2006-02-18
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix
CVE Names: CVE-2004-2069 CVE-2006-0225
---------------------------------------------------------------------

---------------------------------------------------------------------
1. Topic:

Updated openssh packages that fix security issues are now available.

OpenSSH is OpenBSD's SSH (Secure SHell) protocol implementation. SSH
replaces rlogin and rsh, and provides secure encrypted communications
between two untrusted hosts over an insecure network. X11 connections
and arbitrary TCP/IP ports can also be forwarded over a secure channel.
Public key authentication can be used for "passwordless" access to
servers.

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386
Fedora Core 2 - i386
Fedora Core 3 - i386, x86_64

3. Problem description:

A bug was found in the way the OpenSSH server handled the MaxStartups
and LoginGraceTime configuration variables. A malicious user could
connect to the SSH daemon in such a way that it would prevent additional
logins from occuring until the malicious connections are closed. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2004-2069 to this issue.

The scp command was found to expose filenames twice to shell expansion.
A malicious user could execute arbitrary commands by using specially
crafted filenames containing shell metacharacters or spaces. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
name CVE-2006-0225 to this issue.

Users of openssh should upgrade to these updated packages, which contain
backported patches to resolve these issues.

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 yum and apt. Many
people find this an easier way to apply updates. To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system. This assumes that you
have yum or apt-get configured for obtaining Fedora Legacy content.
Please visit http://www.fedoralegacy.org/docs for directions on how to
configure yum and apt-get.
