INITIAL RELEASE:

POTENTIAL SECURITY IMPACT:
Increase in privilege.

VULNERABILITY SUMMARY:
A potential security vulnerability has been identified with HP Serviceguard running on 
HP-UX and Linux that may allow remote unauthorized privileges.

SUPPORTED SOFTWARE VERSIONS*:  ONLY impacted versions are listed. HP-UX
HP Serviceguard                    A.11.13, A.11.14, A.11.15.00,
                                            A.11.16.00
HP Cluster Object Manager   A.01.03, B.01.04, B.02.02.00,
                                          B.03.00.00, B.03.00.01

Linux
HP Serviceguard for Linux    A.11.14.04, A.11.15.04
HP Cluster Object Manager   B.02.01.02, B.02.02.02

BACKGROUND:
Serviceguard was designed to operate within a single security domain. This includes 
the following requirements:

1. The root user on any node inside the trusted network must be trusted by all nodes. 
Users with appropriate privileges on any node inside the  trusted network must be 
trusted by all nodes. This includes the root user on any Unix computer and any valid 
user on a Windows computer. 2. The network must be physically defended against any 
spoof or sniff attacks. 3. The network firewalls must be correctly configured to defend 
against external attacks.

A defect was discovered which allows non-root users on the subnet to obtain elevated 
privileges. The available patches, together with their special installation instructions, 
fix that defect. Any system on which Serviceguard has been installed (all configurations 
using SGeRAC, SGeSAP, Continentalcluster, and
Metrocluster) should be patched, including those which are
not configured in a cluster.

For more information, a white paper entitled "Securing Serviceguard" has been written 
and posted at http://docs.hp.com/hpux/ha

Note: In the listings below on Linux versions, IA32 and
IA64 represent the 32 and 64 bit Intel Architecture CPU's, while PA represents the 
Precision Architecure from HP.

The Linux files are packaged as a tar'ed  shar'ed RPM. Download, unshar and extract 
the tar package, then run "sgupdate"  to install the new version.

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.

The HP-UX Security Patch Matrix, updated daily, categorizes security patches by 
platform/OS release, and by Bulletin topic. The Security Patch Check tool completely 
automates the process of reviewing the Security Patch Matrix for HP-UX 11.XX Versions.

NOTE: Installing patches listed in the Security Patch Matrix will completely implement 
the RESOLUTION in the Security Bulletin _only_ if there are no MANUAL ACTIONS included.

The Security Patch Check tool can also verify that a Security Bulletin RESOLUTION has 
been implemented on HP-UX 11.XX Versions provided that no MANUAL ACTIONS were included. 
The Security Patch Check tool cannot verify patches implemented via product upgrade.
