See Security Bulletin SSRT2275 for details. HP Tru64 UNIX 5.1 PK6 (BL20) For the versions listed below, the corrections provided in this advisory DO intersect with previous Early Release Patch Kit (ERP) corrections provided for the SSRT2275- Potential Buffer Overflows Vulnerability. Please note that ONLY the intersecting files that affect libc have been merged with the previous SSRT2275- Potential Buffer Overflows Vulnerability patch kits for these versions as indicated. HP Tru64 UNIX 5.0A PK3 (BL17) HP Tru64 UNIX 4.0F PK7 (BL18) HP Tru64 UNIX 4.0G PK3 (BL17) These patches can be installed on top of the SSRT2275- Potential Buffer Overflows Vulnerability patchkit or standalone. However, in order to get the complete set of fixes included in the SSRT2275 - Potential Buffer Overflows Vulnerability , the appropriate SSRT2275 Potential Buffer Overflows Vulnerability patch kit must be installed before installing this patch kit. Please refer to the following web site for more details regarding the SSRT2275 Potential Buffer Overflows Vulnerability: http://h30097.www3.hp.com/unix/security-download.html For the following versions, the corrections provided in SSRT2275 and SSRT2322 are included in the aggregate patch BL kits. Therefore, the patch kits listed in this Security Bulletin DO NOT have file intersections with other available Early Release Patch (ERP) kits. HP Tru64 UNIX 5.1B PK1 (BL1) HP Tru64 UNIX 5.1A PK4 (BL21) Please review the README file for each patch prior to installation. Early Release Patch Kits Early Release Patches (ERPs) are now available for all supported versions of HP Tru64 UNIX. The ERP kits use dupatch to install and will not install over any Customer Specific Patches (CSPs) which have file intersections with the ERPs. Contact your normal support channel and request HP Tru64 services elevate a case to Support Engineering if a CSP must be merged with one of the ERPs. Important Post-Installation Information 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 HP Tru64 UNIX/TruCluster Server 5.1B PREREQUISITE: V5.1B PK1 (BL1) installed ERP Kit Name: T64V51BB1-C0006700-17362-ES-20030313.tar Kit Location: ftp://ftp1.support.compaq.com/public/unix/v5.1b/ HP Tru64 UNIX/TruCluster Server 5.1A PREREQUISITE: V5.1A PK4 (BL21) installed ERP Kit Name: T64V51AB21-C0108400-17361-ES-20030313.tar Kit Location: ftp://ftp1.support.compaq.com/public/unix/v5.1a/ HP Tru64 UNIX/TruCluster Server 5.1 PREREQUISITE: V5.1 with PK6 (BL20) installed ERP Kit Name: T64V51B20-C0173100-17539-ES-20030324.tar Kit Location: ftp://ftp1.support.compaq.com/public/unix/v5.1/ Please Note: This kit contains additional corrections for SSRT2275 Potential Buffer Overflow Vulnerability.

The fixes contained in the ERP kits will be available in the following mainstream patch kits: HP Tru64 UNIX 5.1B PK2 HP Tru64 UNIX 5.1A PK5 HP Tru64 UNIX 4.0G PK4 HP Tru64 UNIX 4.0F PK8 MD5 and SHA1 checksums are available in the public patch notice for the ERP kits. You can find information on how to verify MD5 and SHA1 checksums at: http://www.support.compaq.com/patches/whats-new.shtml After completing the update, HP and Compaq strongly recommend that you perform an immediate backup of the system disk so that any subsequent restore operationsbegin with updated software. Otherwise, the updates must be re-applied after a future restore operation. Also, if at some future time the system is upgraded to a later patch release or version release, reinstall the appropriate ERP. SUPPORT: For further information, contact HP Services.
