These potential vulnerabilities may be in the form of Local and Remote security domain risks. HP has corrected these potential vulnerabilities. Severity is (HIGH) on all the following potential vulnerabilities: - SSRT2322 Bind resolver exploit in ISC - SSRT2341 calloc() potential overflow - SSRT2384 TCP exploit denies all RPC service - SSRT2412 portmapper hang after port scan with C2 enabled - SSRT2439 xdrmem_getbytes() potential overflow 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 4.0F Patch Kit 8. 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 patchkit is designed to install standalone or over previous ERP patch kit 674.05 - SSRT2275 - Potential Buffer Overflow and contains some but not all of the fixes included in SSRT2275. If you require all the fixes in ERP SSRT2275 you should install the SSRT2275 patch kit prior to installing the patch kit contained in this ERP. 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. 4) These patches deliver updated static libraries. Customers who have applications that build against the affected static libraries should relink those applications post-ERP installation. The following static libraries are updated if the applicable static library subsets are installed on the system being patched: /usr/ccs/lib/libc.a OSFCMPLRS /usr/ccs/lib/libc_r.a OSFCMPLRS INSTALLATION PREREQUISITES: You must have installed HP Tru64 UNIX 4.0F PK7 (BL18) prior to installing this Early Release Patch Kit. KNOWN PROBLEMS WITH THE PATCH KIT: None. RELEASE NOTES FOR DUV40FB18-C0092704-17602-ES-20030327: Release Notes This document summarizes the contents and special instructions for the Digital UNIX V4.0F 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 SSRT2322 SSRT2341 SSRT2384 SSRT2412 SSRT2439 * for Digital UNIX V4.0F DUV40FB18AS0007-20020102.tar (BL18) 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 > copy the kit to /tmp/CSPkit1 > tar -xpvf DUV40D13-C0044900-1285-20000328.tar > cd patch_kit > ./dupatch 2 Special Instructions There are no special instructions for Digital UNIX V4.0F Patch C927.04 3 Summary of CSPatches contained in this kit Digital UNIX V4.0F PatchId Summary Of Fix ---------------------------------------- C927.04 Fix for SSRT2322,2384,2341,2439,2412 4 Additional information from Engineering None 5 Affected system files This patch delivers the following files: Digital UNIX V4.0F Patch C927.04 ./sbin/mount CHECKSUM: 03982 584 SUBSET: OSFBASE440 ./sbin/umount CHECKSUM: 43614 368 SUBSET: OSFBASE440 ./shlib/.upd..libc.so CHECKSUM: 27736 1633 SUBSET: OSFBASE440 ./shlib/.upd..libc_r.so CHECKSUM: 27736 1633 SUBSET: OSFBASE440 ./usr/bin/uptime CHECKSUM: 25837 376 SUBSET: OSFBASE440 ./usr/bin/w CHECKSUM: 25837 376 SUBSET: OSFBASE440 ./usr/ccs/lib/libc.a CHECKSUM: 38385 2017 SUBSET: OSFCMPLRS440 ./usr/ccs/lib/libc_r.a CHECKSUM: 38385 2017 SUBSET: OSFCMPLRS440 ./usr/sbin/runclass CHECKSUM: 26030 272 SUBSET: OSFBASE440 ./usr/sbin/ypbind CHECKSUM: 29177 504 SUBSET: OSFCLINET440 [R] UNIX is a registered trademark in the United States and other countries licensed exclusively through X/Open Company Limited.
