Summary
Red Hat Security Advisory: openssh security update

Notes

Topic
Updated openssh packages that fix a potential security vulnerability and various other bugs are now available for Red Hat Enterprise Linux 2.1. This update has been rated as having low security impact by the Red Hat Security Response Team.
Details
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 bug: On systems in which 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. Users of openssh should upgrade to these updated packages, which contain backported patches to resolve these issues.

Only those\nRPMs which are currently installed will be updated.  Those RPMs which are\nnot installed but included in the list will not be updated.  Note that you\ncan also use wildcards (*.rpm) if your current directory *only* contains the\ndesired RPMs.\n\nPlease note that this update is also available via Red Hat Network.  Many\npeople find this an easier way to apply updates.  To use Red Hat Network,\nlaunch the Red Hat Update Agent with the following command:\n\nup2date\n\nThis will start an interactive process that will result in the appropriate\nRPMs being upgraded on your system.\n\nIf up2date fails to connect to Red Hat Network due to SSL\nCertificate Errors, you need to install a version of the\nup2date client with an updated certificate.  The latest version of\nup2date is available from the Red Hat FTP site and may also be\ndownloaded directly from the RHN website:\n\nhttps://rhn.redhat.com/help/latest-up2date.pxt",
