RESOLUTION
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. Please review the README file for
each patch prior to installation.
NOTE: These ERPs supercede ERPs delivered with the release
of SSRT2257 HP Tru64 UNIX /usr/bin/su buffer overflow
