The vulnerability could be exploited remotely to allow an authorized remote attacker to execute arbitrary code or cause a denial of service (DoS). 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. The patches in this ERP kit will also be available in the next mainstream patch kit - HP Tru64 UNIX V5.1B-5. 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 V5.1B-3 PK5 (BL26) prior to installing this Early Release Patch Kit. SUPERSEDE INFORMATION: None KNOWN PROBLEMS WITH THE PATCH KIT: None. RELEASE NOTES FOR T64KIT1001467-V51BB26-ES-20080314: 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 SSRT080011 * for Tru64 UNIX V5.1B NewFilesTCR.tar (BL26) * for Tru64 UNIX V5.1B T64V51BB26AS0005-20050502.tar (BL26) This kit includes a patch which requires system reboot. 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 SPECIAL INSTRUCTIONS for Tru64 UNIX V5.1B Patch C2270.00 3 Summary of CSPatches contained in this kit Tru64 UNIX V5.1B PatchId Summary Of Fix ---------------------------------------- C2270.00 Fix for SSRT080011 4 Additional information from Engineering None 5 Affected system files This patch delivers the following files: Tru64 UNIX V5.1B Patch C2270.00 ./usr/ssh/bin/scp2 CHECKSUM: 47135 1286 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/sftp-server2 CHECKSUM: 41994 1682 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/sftp-server2.static CHECKSUM: 44428 2758 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/sftp2 CHECKSUM: 28187 1352 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-add2 CHECKSUM: 57657 1836 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-agent2 CHECKSUM: 47110 1861 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-askpass2 CHECKSUM: 45429 216 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-certenroll2 CHECKSUM: 49184 1800 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-chrootmgr CHECKSUM: 33171 4 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-dummy-shell CHECKSUM: 52742 196 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-dummy-shell.static CHECKSUM: 30154 581 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-hostbased-setup CHECKSUM: 07871 4 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-keygen2 CHECKSUM: 09010 1824 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-probe2 CHECKSUM: 07144 232 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-pubkeymgr CHECKSUM: 50341 7 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-signer2 CHECKSUM: 51084 1858 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh-validate-conf CHECKSUM: 16788 8 SUBSET: OSFSSHBASE540 ./usr/ssh/bin/ssh2 CHECKSUM: 41894 2268 SUBSET: OSFSSHBASE540 ./usr/ssh/sbin/srcmd CHECKSUM: 37876 50 SUBSET: OSFSSHBASE540 ./usr/ssh/sbin/sshd-check-conf CHECKSUM: 26754 1785 SUBSET: OSFSSHBASE540 ./usr/ssh/sbin/sshd2 CHECKSUM: 52500 2286 SUBSET: OSFSSHBASE540 ./usr/ssh/shlib/libsshrcmd.so CHECKSUM: 01142 39 SUBSET: OSFSSHBASE540 ./usr/ssh/shlib/libssht64p.so CHECKSUM: 15054 4494 SUBSET: OSFSSHBASE540 [R] UNIX is a registered trademark in the United States and other countries licensed exclusively through X/Open Company Limited.
