INITIAL RELEASE: 08 August 2004
POTENTIAL SECURITY IMPACT: Data file corruption
SOURCE: HEWLETT-PACKARD COMPANY
HP Software Security Response Team
REFERENCES: 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:
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
