    HEWLETT-PACKARD COMPANY SECURITY BULLETIN: #0165,
    Originally issued: 28 August '01
 ----------------------------------------------------------------------
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:  Security vulnerability in HP Process Resource Manager
          (PRM) product revision C.01.08.2 and earlier, on all
          releases of HP-UX.

PLATFORM: HP 9000 Series 700/800 running HP-UX 10.20, HP-UX 11.00,
          and HP-UX 11.11.

DAMAGE:   Potential for non-root user to gain root/superuser
          priviledges.

SOLUTION: Install the appropriate patch for the correct product
          and OS release:
           HP-UX 10.20             PRM C.01.07       PHSS_24863
           HP-UX 11.00/11.11       PRM C.01.08.2     PHSS_24864

MANUAL ACTIONS: none

AVAILABILITY:   The patches are currently available.
 ----------------------------------------------------------------------

A. Background

   A vulnerability exists in /opt/prm/bin for versions up to and
   including PRM C.01.08.2.  Non-root users can potentially alter
   libraries and environment variables to gain root-level access.
   Since HP-UX Workload Manager (WLM) uses PRM to control resources,
   the vulnerability also exists for this software.

B. Recommended solution

   Application of the appropriate patch selected from the list below
   completely solves this problem:

      PRM revision C.01.07 on HP-UX 10.20         PHSS_24863
      PRM revision C.01.08.2 on HP-UX 11.x        PHSS_24864

   NOTE:
   If you are not currently at one of the above revisions of PRM for
   the given OS versions, it is highly recommended that you upgrade.
   To determine which version of PRM is installed, use the command
   "what /usr/bin/prmconfig".

   For HP-UX 11.x, PRM C.02.00 will be available on the
   September 2001 HP-UX Application Release media which addresses
   the problem.

   The problem can also be eliminated by installing the upcoming
   revision of the product, PRM C.02.00, from the September 2001
   HP-UX Application Release media.
   Customers who have HP-UX Workload Manager (WLM) installed should
   upgrade their PRM version to C.01.08.2 and install the appropriate
   patch, or install PRM C.02.00 from the September 2001 HP-UX
   Application Release media.
