Vulnerability Assessment Details

RHSA-2002-131: openssh

Vulnerability Assessment Summary
Check for the version of the openssh packages

Detailed Explanation for this Vulnerability Assessment

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

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.
