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.

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

Title: Sec. Vulnerability in PRM
----------------------------------------------------------------------
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.
