VULNERABILITY SUMMARY

Tru64 UNIX operating systems running IPSEC, which uses the
Internet Security Association and Key Management Protocol
(ISAKMP). The vulnerabilities could be exploited remotely to cause
Denial of Service (DoS) .

The following supported versions of HP Tru64 UNIX are affected:

    * HP Tru64 UNIX 5.1B-3

BACKGROUND

RESOLUTION

Until the corrections are available in a mainstream release patch
kit, 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 ERP
installation is blocked by any of your installed CSPs.

Note: these ERPs also include the corrections previously released
in HPSBTU01217/SSRT5957 (HP Tru64 UNIX IPSEC Tunnel ESP Mode
Remote Unauthorized Disclosure of Encrypted Data).
