SecurityTracker: HP-UX Process Resource Manager Bug Lets Local Users Corrupt Files

n/a
VULNERABILITY SUMMARY:
A potential security vulnerability has been identified with HP Process Resource Manager on
all OS versions running PRM C.02.01[.01] and prior. HP PRM is also used in Workload
Manager, so affects WLM version A.02.01 and prior as well.

This vulnerability could potentially be exploited to corrupt data on a system running PRM.
SUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed.
PRM C.02.01[.01] and prior WLM A.02.01 and prior.
BACKGROUND:
For a PGP signed version of this bulletin please write to security-alert@hp.com

A vulnerability exists in PRM for versions up to and including C.02.01[.01]. Non-root
users can potentially cause data file corruption on a system with PRM installed. Because
HP-UX Workload Manager (WLM) uses PRM to control resources, the vulnerability also exists
for this software.

AFFECTED VERSIONS

Note: To determine if a system has an affected version,
search the output of "swlist -a revision -l fileset"
for an affected fileset. Then determine if the
recommended patch or update is installed.

HP-UX B.11.00
HP-UX B.11.11
HP-UX B.11.23
=============

Proc-Resrc-Mgr.PRM-RUN

PRM-Sw-Lib.PRM-LIB

action: install revision C.02.02 or subsequent

WLM-Monitor

Workload-Mgr

action: install revision A.02.02 or subsequent

END AFFECTED VERSIONS

NOTE: Although this security vulnerability is completely solved by upgrading the product,
there are patches available for PRM C.02.02 and WLM A.02.02 that fix various other
non-security issues. HP recommends installing these patches corresponding to the
applicable OS:

HP-UX B.11.00/B.11.11 PRM C.02.02/ WLM A.02.02 PHSS_30985
HP-UX B.11.23 PRM C.02.02/ WLM A.02.02 PHSS_30986
RESOLUTION:
Upgrading to the appropriate PRM and WLM revisions completely solves this problem:

HP-UX B.11.00, B.11.11, B.11.23 PRM C.02.02 WLM A.02.02

PRM C.02.02 can be installed from the March 2004 HP-UX Application Release media. To
determine which version of PRM is installed, use the command "what /usr/bin/prmconfig".

NOTE: Customers who have HP-UX Workload Manager (WLM) installed should upgrade their WLM
version to A.02.02 as well. WLM A.02.02 is also part of the March 2004 HP-UX Application
Release media. To determine which version of WLM is installed, use the command
"/opt/wlm/bin/wlmd -V".

MANUAL ACTIONS: Yes - Update
Upgrading to the appropriate PRM or WLM revisions from the list below completely solves
this problem:

HP-UX B.11.00, B.11.11, B.11.23 PRM C.02.02 WLM A.02.02
