Summary
Red Hat Security Advisory: : : : Updated OpenSSH packages fix various security issues

Notes

Topic
Updated openssh packages are now available for Red Hat Linux 7, 7.1, 7.2, and 7.3. These updates fix an input validation error in OpenSSH. [Updated 16 April 2003] Added packages for Red Hat Linux on IBM iSeries and pSeries systems.
Details
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. Please note that this option 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. [Update 6/28/2002] Added packages for Red Hat Linux 7.2 for s390.
