The information in the following Security Bulletin should be acted upon
as soon as possible.  Hewlett-Packard Company will not be liable for any
consequences to any customer resulting from customer's failure to fully
implement instructions in this Security Bulletin as soon as possible.

PROBLEM:  Programs running on the VirtualVault may receive data
          inappropriately via an interface configured with aliased
          IP addresses.

PLATFORM: HP9000 Series 7/800 running only HP-UX 11.04 (VVOS).

DAMAGE:   Unprivileged processes may receive remote data unexpectedly.

SOLUTION: Apply the patch noted below.

AVAILABILITY: The patch is currently available.

  A. Background
     HP-UX 11.04 (VVOS) introduced a vulnerability in the network
     layer of the operating system that could allow data to be
     delivered via a network interface to unprivileged processes if
     multiple IP addresses are assigned to the interface.

  B. Fixing the problem
     This problem can be eliminated by installing the following patch.

         HP-UX 11.04 (VVOS):              PHNE_21261

     Note: A system reboot will be required.  There is no
           corresponding problem with HP-UX 10.24 (VVOS).
