New Kit Date: 01-AUG-2002 Modification Date: Not Applicable Modification Type: New Kit PRODUCT: Tru64 UNIX [R] 4.0F SOURCE: Hewlett-Packard Company ECO INFORMATION: ECO Name: DUV40FB18-C0067403-14947-ES-20020730 ECO Kit Approximate Size: 11MB Kit Applies To: Tru64 UNIX 4.0F PK7 (BL18) ECO Kit CHECKSUMS: /usr/bin/sum results: 61755 10760 /usr/bin/cksum results: 749407845 11018240 MD5 results: 44915ab6040aed9ff8674a49fed5f083 SHA1 results: cc905b1dc5039f039484afa9913c911c9aa4fada ECO KIT SUMMARY: A dupatch-based, Early Release Patch kit exists for Tru64 UNIX 4.0F that contains solutions to the following problem(s): Several potential security vulnerabilities have been identified in the HP Tru64 UNIX operating system that may allow non-privileged users to gain unauthorized (root) access. This may be in the form of local security domain risks. The potential security vulnerability in the following commands have been corrected: - SSRT2257 /usr/bin/su (Severity - High) - SSRT2190 /usr/bin/chsh (Severity - Medium) - SSRT2192 /usr/bin/passwd (Severity - Medium) - SSRT2259 /usr/bin/chfn (Severity - Medium) - SSRT2262 /usr/tcb/bin/dxchpwd (Severity - Medium) Tru64 UNIX has integrated the fixes delivered for SSRTM541 in duv40fb18-c0067302-14158-es-20020429.tar into this ERP kit because both needed to update libc This ERP kit can be used if you have and have not installed the patches delivered for SSRTM541. For more information regarding SSRTM541 see Security Bulletin: Titled: (SSRTM541) Tru64 UNIX CDE, NFS and NIS related Potential Security Vulnerabilities Located: http://wwss1pro.compaq.com/support/reference_library/ 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 - Tru64 UNIX 4.0F Patch Kit 8. INSTALLATION NOTES: 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. This ERP kit will NOT install over any installed 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 Tru64 UNIX 4.0F PK7 (BL18) prior to installing this Early Release Patch Kit. SUPERSEDED PATCH LIST This ERP kit will install over the patches delivered for SSRT-541/SSRTM541. KNOWN PROBLEMS WITH THE PATCH KIT: 1) Use the MAJOR (nnn.) patch identifiers in the Special Instructions contained in this patch kit. The MINOR (.nn) patch identifiers in the special instructions are incorrect. RELEASE NOTES FOR DUV40FB18-C0067403-14947-ES-20020730: 1 Release Notes This Early Release Patch Kit Distribution contains: - fixes that resolve the problem(s) reported in: o SSRT-541 SSRT0752U SSRT0753U SSRT0757U SSRT0771U SSRT0781U SSRT0782U SSRT0788U SSRT2190 SSRT2192 SSRT2257 SSRT2259 SSRT2262 * 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 > > 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 C674.03 SPECIAL INSTRUCTIONS for Digital UNIX V4.0F Patch C673.03 - The patches in this kit REQUIRE installation of: Tru64 UNIX 4.0F Patch Kit 7 (DUV40FB18AS0007-20020102.tar). - Select all patches in this kit for installation. - The patches in this kit deliver files for mandatory and optional install Operating System subsets.
