The following potential security vulnerabilities have been corrected: SSRT3629B - SSH (Severity - High) The Patch Kit Installation Instructions and the Patch Summary and Release Notes documents provide patch kit installation and removal instructions and a summary of each patch. Please read these documents prior to installing patches on your system. Note: The same ERP kit applies to 5.1B BL22 and BL24. The patches in this ERP kit will also be available in the next mainstream patch kit - HP Tru64 UNIX 5.1B Patch Kit 4. INSTALLATION NOTES: 1) Install this kit with the dupatch utility that is included in the patch kit. You may need to baseline your system if you have manually changed system files on your system. The dupatch utility provides the baselining capability. 2) The patch in this ERP kit does not have any file intersections with any other ERP available at this time for this product version. 3) This ERP kit will NOT install over any Customer Specific Patches (CSPs) which have file intersections with this ERP kit. Contact your normal Service Provider for assistance if the installation of this ERP kit is blocked by any of your installed CSPs. INSTALLATION PREREQUISITES: You must have installed HP Tru64 UNIX 5.1B PK3 (BL24) prior to installing this Early Release Patch Kit. KNOWN PROBLEMS WITH THE PATCH KIT: None. RELEASE NOTES FOR T64KIT0020964-V51BB24-ES-20031204: Release Notes This document summarizes the contents and special instructions for the Tru64 UNIX V5.1B patches contained in this kit. For information about installing or removing patches, baselining, and general patch management, see the Patch Kit Installation Instructions document. 1 Release Notes This Early Release Patch Kit Distribution contains: - fixes that resolve the problem(s) reported in: o 221-2-273 SSRT3629B * for Tru64 UNIX V5.1B T64V51BB24AS0003-20030929.tar (BL24) The patches in this kit are being released early for general customer use. Refer to the Release Notes for a summary of each patch and installation prerequisites. Patches in this kit are installed by running dupatch from the directory in which the kit was untarred. For example, as root on the target system: > mkdir -p /tmp/CSPkit1 > cd /tmp/CSPkit1 > > tar -xpvf DUV40D13-C0044900-1285-20000328.tar > cd patch_kit > ./dupatch 2 Special Instructions There are no special instructions for Tru64 UNIX V5.1B Patch C409.01 3 Summary of CSPatches contained in this kit Tru64 UNIX V5.1B PatchId Summary Of Fix ---------------------------------------- C409.01 Fix for SSRT3629B, ssh 4 Additional information from Engineering None 5 Affected system files This patch delivers the following files: Tru64 UNIX V5.1B Patch C409.01 ./etc/ssh2/ssh2_config.template CHECKSUM: 00983 3 SUBSET: OSFSSHBASE540 ./etc/ssh2/ssh_dummy_shell.out.template CHECKSUM: 60278 1 SUBSET: OSFSSHBASE540 ./etc/ssh2/sshd2_config.template CHECKSUM: 25132 7 SUBSET: OSFSSHBASE540 ./etc/ssh2/subconfig/anonymous.example CHECKSUM: 38279 1 SUBSET: OSFSSHBASE540 ./etc/ssh2/subconfig/host_ext.example CHECKSUM: 44315 1 SUBSET: OSFSSHBASE540 ./etc/ssh2/subconfig/host_int.example CHECKSUM: 08947 1 SUBSET: OSFSSHBASE540 ./etc/ssh2/subconfig/user.example CHECKSUM: 27257 1 SUBSET: OSFSSHBASE540 ./sbin/init.d/sshd CHECKSUM: 52078 4 SUBSET: OSFSSHBASE540 ./usr/lib/nls/msg/en_US.ISO8859-1/srcmd.cat CHECKSUM: 50346 3 SUBSET: OSFSSHBASE540 ./usr/lib/nls/msg/en_US.ISO8859-1/ssh2.cat CHECKSUM: 10915 100 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/scp2 CHECKSUM: 03273 1136 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/sftp-server2 CHECKSUM: 05932 1440 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/sftp-server2.static CHECKSUM: 42775 2313 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/sftp2 CHECKSUM: 17559 1176 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-add2 CHECKSUM: 56461 1568 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-agent2 CHECKSUM: 01870 1584 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-askpass2 CHECKSUM: 05019 186 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-certenroll2 CHECKSUM: 54090 1536 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-chrootmgr CHECKSUM: 25465 4 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-dummy-shell CHECKSUM: 42966 170 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-dummy-shell.static CHECKSUM: 59775 490 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-hostbased-setup CHECKSUM: 13746 4 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-keygen2 CHECKSUM: 18750 1560 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-probe2 CHECKSUM: 22616 202 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-pubkeymgr CHECKSUM: 06404 7 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-signer2 CHECKSUM: 47620 1584 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-validate-conf CHECKSUM: 49877 8 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh2 CHECKSUM: 09347 1947 SUBSET: OSFSSHBASE540 ./usr/ssh/sbin/srcmd CHECKSUM: 00314 41 SUBSET: OSFSSHBASE540 ./usr/ssh/sbin/sshd-check-conf CHECKSUM: 00226 1527 SUBSET: OSFSSHBASE540 ./usr/ssh/sbin/sshd2 CHECKSUM: 31471 1971 SUBSET: OSFSSHBASE540 ./usr/ssh/shlib/libsshrcmd.so CHECKSUM: 50659 39 SUBSET: OSFSSHBASE540 ./usr/ssh/shlib/libssht64p.so CHECKSUM: 49829 4485 SUBSET: OSFSSHBASE540 [R] UNIX is a registered trademark in the United States and other countries licensed exclusively through X/Open Company Limited.
