Ärende: [RHSA-2001:161-08] Updated OpenSSH packages available
------------------------------------------------------------
---------------------------------------------------------------------
Red Hat, Inc. Red Hat Security Advisory
Synopsis: Updated OpenSSH packages available
Advisory ID: RHSA-2001:161-08
Issue date: 2001-12-03
Updated on: 2001-12-04
Product: Red Hat Linux
Keywords: openssh uselogin
Cross references:
Obsoletes: RHSA-2001:154
---------------------------------------------------------------------
1. Topic:
Updated OpenSSH packages are now available for Red Hat Linux 7, 7.1, and
7.2. These packages fix a vulnerability which exists when a
server is configured with the "UseLogin" option.
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
3. Problem description:
When the "UseLogin" option is enabled in OpenSSH, a malicious user
who authenticates using key-based authentication methods can
influence the environment variables passed to the login process.
This could allow the user to execute arbitrary code with superuser
privileges. In Red Hat Linux the OpenSSH server has the "UseLogin"
option disabled by default. Therefore, it is not vulnerable unless
the system administrator has changed this setting.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2001-0872 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.
