A number of potential security vulnerabilities have recently been discovered for CDE, libc, NIS and NFS released with Tru64 UNIX 4.0F where under certain circumstances, system integrity may be compromised. Compaq has corrected the following potential security vulnerabilities: - CDE o dtaction potential buffer overflow (SSRT0752U) o ttsession potential buffer overflow (SSRT0753U) o dtprintinfo potential buffer overflow (SSRT0757U) CERT Vulnerability Note #860296 summarizes this potential vulnerability: http://www.kb.cert.org/vuls/id/860296 o dtprintinfo potential corefile write problem (SSRT0788U) CERT Vulnerability Note #860296 summarizes this potential vulnerability: http://www.kb.cert.org/vuls/id/860296 o dtspcd potential buffer overflow (SSRT0782U) Compaq has not been able to reproduce the problem identified in the CERT advisory for any Compaq OS. However with the information available, we are including a code change for TRU64 UNIX that will further reduce any potential overflow vulnerability. CERT Advisory CA-2001-31 and CA-2002-01 summarizes this potential vulnerability: http://www.cert.org/advisories/CA-2001-31.html http://www.cert.org/advisories/CA-2002-01.html - Environment Variable LANG and LOCPATH o libc potential environment variable corruption with LANG and LOCPATH, may cause buffer overflow (SSRT0771U) - NIS o ypbind may core during nmap portscan (SSRT0781U) The following customer-readable Compaq Service Advisory is also available: - Compaq Advisory: (SSRT-541) Tru64 UNIX CDE, NFS and NIS related Potential Security Vulnerabilities http://ftp.support.compaq.com/patches/.new/security.shtml 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 PK8. 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. INSTALLATION PREREQUISITES: You must have installed 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-C0067302-14158-ES-20020429.tar: 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 * 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 SPECIAL INSTRUCTIONS for Digital UNIX V4.0F Patch C673.02 - 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.
