REFERENCES:    N/A

VULNERABILITY SUMMARY:
A potential security vulnerability has been identified in the
HP Tru64  UNIX operating system using IPsec/IKE
(Internet Key Exchange) with  Certificates and may
be remotely exploitable, resulting in unauthorized
privileged access.


SUPPORTED SOFTWARE VERSIONS*:  ONLY impacted versions are listed.

   o HP Tru64 UNIX 5.1B     PK2(BL22), PK3(BL24)
   o HP Tru64 UNIX 5.1A     PK6(BL24)


BACKGROUND:
See Resolution

RESOLUTION:
Until the corrections are available in  mainstream release patch
kits, HP is releasing the following Early Release Patch (ERP) kits
publicly for use by any customer.

The ERP kits use dupatch to install and will not install over any
installed Customer Specific Patches (CSPs) that have file
intersections with the ERPs.  Contact your service provider for
assistance if the installation of the ERPs is blocked by any of
your installed CSPs.

The fixes contained in the ERP kits are scheduled to be available
in the following mainstream patch kit for Tru64 UNIX V5.1B PK4

Corrections for V5.1A are available via web kit and
are not included as part of the Base OS.

Early Release Patches

Note: These ERPs deliver new functionality that allows you to
restrict connection access to an authorized list of remote
identities (IDs) when configuring IPsec/IKE for both a host
and a gateway. Implementing this new functionality is
a 2-Step process: 

    1. Install the 5.1B OS patch kit or the 5.1A web kit on the
        target system
    2. Follow the instructions in the Technical Update listed in
       the resolution section of this Bulletin.
