RESOLUTION
HP-UX:
At the time of writing this document, HP is currently investigating
the potential impact to HP-UX released Operating System software
products. As further information becomes available HP will provide
notice of the availability of any necessary patches through standard
security bulletin announcements and be available from your normal
HP Services support channel.
HP Tru64 UNIX/TruCluster Server:
Early Release Patches (ERPs) are now available for all supported
versions of HP Tru64 UNIX/TruCluster Server. 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. Please review
the README file for each patch prior to installation.
