Summary
Red Hat Security Advisory: : Updated OpenSSH packages fix potential vulnerabilities

Notes

Topic
Updated OpenSSH packages are now available that fix bugs that may be remotely exploitable. [Updated 17 Sep 2003] Updated packages are now available to fix additional buffer manipulation problems which were fixed in OpenSSH 3.7.1. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0695 to these additional issues. We have also included fixes from Solar Designer for some additional memory bugs. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0682 to these issues.
Details
OpenSSH is a suite of network connectivity tools that can be used to establish encrypted connections between systems on a network and can provide interactive login sessions and port forwarding, among other functions. The OpenSSH team has announced a bug which affects the OpenSSH buffer handling code. This bug has the potential of being remotely exploitable. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0693 to this issue. All users of OpenSSH should immediately apply this update which contains a backported fix for this issue.

          "details": "Before applying this update, make sure all previously released errata\nrelevant to your system have been applied.\n\nTo update all RPMs for your particular architecture, run:\n\nrpm -Fvh [filenames]\n\nwhere [filenames] is a list of the RPMs you wish to upgrade.  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 Certificate \nErrors, you need to install a version of the up2date client with an updated \ncertificate.  The latest version of up2date is available from the Red Hat \nFTP site and may also be downloaded directly from the RHN website:\n\nhttps://rhn.redhat.com/help/latest-up2date.pxt",
