Early Release Patches (ERPs) are now available for all
supported versions of HP Tru64 UNIX/TruCluster Server that
provide a solution to this potential vulnerability. 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.

The fixes contained in the ERP kits will be available in
the following mainstream patch kits:

HP Tru64 UNIX 5.1B PK3

After completing the update, HP strongly recommends that you
perform an immediate backup of  the system disk so that any
subsequent restore operations begin with updated software.

restore operation.  Also, if at some future time the system
is upgraded to a later patch release or version release,
reinstall the appropriate ERP.
