Red Hat, Inc. Red Hat Security Advisory
Synopsis: Updated OpenSSH packages fix various security issues
Advisory ID: RHSA-2002:127-18
Issue date: 2002-06-24
Updated on: 2002-06-27
Product: Red Hat Linux
Keywords: security pam openssh ChallengeResponseAuthentication

1. Topic:
Updated openssh packages are now available for Red Hat Linux 7, 7.1, 7.2,
and 7.3. These updates fix an input validation error in OpenSSH.
2. Relevant releases/architectures:
Red Hat Linux 7.0 - alpha, i386
Red Hat Linux 7.1 - alpha, i386, ia64
Red Hat Linux 7.2 - i386, ia64
Red Hat Linux 7.3 - i386
3. Problem description:
OpenSSH provides an implementation of the SSH (secure shell) protocol used
for logging into and executing commands on remote machines.
Versions of the OpenSSH server between 2.3.1 and 3.3 contain an input
validation error that can result in an integer overflow and privilege
escalation.
At this time, Red Hat does not believe that the default installation of
OpenSSH on Red Hat Linux is vulnerable to this issue; however a user would
be vulnerable if the configuration option "PAMAuthenticationViaKbdInt" is
enabled in the sshd configuration file (it is not enabled by default).
We have applied the security fix provided by the OpenSSH team to these
errata packages which are based on OpenSSH 3.1p1. This should minimize the
impact of upgrading to our errata packages.
All users of OpenSSH should update to these errata packages which are not
vulnerable to 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.
