August 29, 2001 20:00 GMT                                         Number L-136
PROBLEM:       Due to an existing vulnerability in /opt/prm/bin, non-root 
               users can alter libraries and environment variables. 
PLATFORM:      HP 9000 Series 700/800 running HP-UX 10.20, HP-UX 11.00, and 
               HP-UX 11.11.
               Patches are available for the following:
                    OP SYS            Product Release            Patch 
                    HP-UX 10.20       PRM C.01.07                PHSS_24863
                    HP-UX 11.00/11.11 PRM C.01.08.2              PHSS_24864 
DAMAGE:        Through the ability to alter the libraries/variables a non-root 
               user is able to compromise the system by gaining root access. 
SOLUTION:      If your system is not up to the revision of PRM listed, HP 
               strongly recommends that you upgrade. This is also true if you 
               have HP-UX Workload Manager (WLM) on your system. A new version 
               of PRM will be available in the September 2001 HP-UX 
               Application Release media.

               If you have the listed revision apply the patch as specified by
               HP, for the listed revisions/systems.

               To check which version of PRM exists on your system use the
               command: "what /usr/bin/prmconfig". 
VULNERABILITY  The risk is MEDIUM. The capability of gaining root access 
ASSESSMENT:    exists.

      Title:  Sec. Vulnerability in PRM

    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
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

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


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

   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.
