A potential vulnerability has been identified on the HP Tru64 UNIX operating system running DNS BIND. The vulnerability could be exploited remotely to gain unauthorized privileged access through the use of DNS cache poisoning. HP has addressed the following potential vulnerability: SSRT051007 - DNS (Domain Name System) (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. 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) 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 V4.0G PK4 (BL22) prior to installing this Early Release Patch Kit. SUPERSEDE INFORMATION: T64KIT1000521-V40GB22-ES-20060410.tar replaces T64KIT1000211-V40GB22-ES-20051210.tar KNOWN PROBLEMS WITH THE PATCH KIT: None. RELEASE NOTES FOR T64KIT1000521-V40GB22-ES-20060410: Release Notes This document summarizes the contents and special instructions for the Tru64 UNIX V4.0G 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 2 * for Tru64 UNIX V4.0G T64V40GB22AS0004-20030731.tar (BL22) 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 V4.0G Patch C386.04 After installing the patch, on a system configured to be bind server execute rcmgr set BIND_SERVERARGS "-c /etc/namedb/named.conf" and for on a cluster, rcmgr -c set BIND_SERVERARGS "-c /etc/namedb/named.conf" "named" in BIND 9 no longer takes '-b' switch to pass configuration file parameter, instead it uses '-c' switch to do it. Execute following command for the new "named" to take effect, /sbin/init.d/named /sbin/init.d/named start NOTE : 1. use named-checkconf and named-checkzone commands to verify that the configuration files confirm to Bind 9. e.g. named-checkconf named-checkzone example.com /etc/namedb/hosts.db 2. CNAME entries no longer accept quotes. e.g. "hosts-1" IN CNAME A needs to be changed to hosts-1 IN CNAME A SPECIAL INSTRUCTIONS for Tru64 UNIX V4.0G Patch C387.00 All the DNSSEC features in Bind 9 are supported only on v5.1B. NOTE : DNSSEC features in Bind 9 which depend upon OpenSSL, are NOT supported on following OS versions, - Digital Unix v4.0F - Digital Unix v4.0G - Tru64 v5.1A 3 Summary of CSPatches contained in this kit Tru64 UNIX V4.0G PatchId Summary Of Fix ---------------------------------------- C386.04 Bind 9 release.
