The information in this Security bulletin should be acted upon as soon as possible. INITIAL RELEASE: 21 October 2004 POTENTIAL SECURITY IMPACT: Increase in privilege. SOURCE: HEWLETT-PACKARD COMPANY HP Software Security Response Team REFERENCES: None 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.
