RHEL 3 : openssh (RHSA-2005:106)

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated openssh packages that fix a potential security vulnerability
and various other bugs are now available for Red Hat Enterprise Linux

This update has been rated as having low security impact by the Red
Hat Security Response Team.

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 CVE-2004-0175 to this

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.
