    Synopsis:          Low: openssh security update
    Advisory ID:       RHSA-2005:106-01
    Advisory URL:      https://rhn.redhat.com/errata/RHSA-2005-106.html
    Issue date:        2005-05-18
    Updated on:        2005-05-18
    Product:           Red Hat Enterprise Linux
    CVE Names:         CAN-2004-0175
    - ---------------------------------------------------------------------
    
    1. Summary:
    
    Updated openssh packages that fix a potential security vulnerability and
    various other bugs are now available for Red Hat Enterprise Linux 3.
    
    This update has been rated as having low security impact by the Red Hat
    Security Response Team.
    
    2. Relevant releases/architectures:
    
    Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
    Red Hat Desktop version 3 - i386, x86_64
    Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
    Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64
    
    3. Problem description:
    
    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.
    
    The scp protocol allows a server to instruct a client to write to arbitrary
    files outside of the current directory. This could potentially cause a
    security issue if a user uses scp to copy files from a malicious server.
    The Common Vulnerabilities and Exposures project (cve.mitre.org) has
    assigned the name CAN-2004-0175 to this issue.
    
    These updated packages also correct the following bugs:
    
    On systems where direct ssh access for the root user was disabled by
    configuration (setting "PermitRootLogin no"), attempts to guess the root
    password could be judged as sucessful or unsucessful by observing a delay.
    
    On systems where the privilege separation feature was turned on, the user
    resource limits were not correctly set if the configuration specified to
    raise them above the defaults.  It was also not possible to change an
    expired password.
    
    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 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
