RHEL 2.1 : openssh (RHSA-2002:131)

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

Updated openssh packages are now available for Red Hat Linux Advanced
Server. These updates fix an input validation error in OpenSSH.

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.
