HP Helion Eucalyptus Security Advisory

Severity Level: 
Issue Date: 
Last Updated: 
Affected Products: 
HP Helion Eucalyptus 3.2.x, 3.1.x


The PostgreSQL security team has released a security advisory identifying an argument injection vulnerability in PostgreSQL 9.1. Although the primary privilege escalation vulnerability does not affect HP Helion Eucalyptus, this vulnerability does make HP Helion Eucalyptus 3.1 and 3.2 potentially vulnerable to remote Denial of Service attacks. HP Helion Eucalyptus 3.3.0 resolves this issue and a workaround is available for the earlier versions.


PostgreSQL is used as a primary database by a number of HP Helion Eucalyptus components to store their metadata and user information. The database is co-located with the Cloud Controller component (CLC) and accepts remote connections. The argument injection vulnerability identified in PostreSQL 9.1 allows remote unauthenticated attackers to corrupt database files and cause the database server to crash and allows remote authenticated users to modify configuration settings and execute arbitrary code. HP Helion Eucalyptus is not affected by the vulnerability that allows attacks from remote authenticated users because the Postgres database is exclusively used by HP Helion Eucalyptus components and no other users exists in the database. However, because of this vulnerability, HP Helion Eucalyptus 3.1 and 3.2 is vulnerable to DoS attacks. HP Helion Eucalyptus deployments that restrict network access to CLC are potentially less vulnerable than deployments where public access is allowed.


Network access to the TCP port 8777 on CLC should be restricted to connections from the CLC, Walrus, Storage Controller (SC), and VMWareBroker (VB) HP Helion Eucalyptus components only. In High Availability ( HA) mode, access to port 8777 should be allowed from both primary and secondary components (CLC, Walrus, SC, and VB). If iptables is used to restrict access to the database on the deployments where the CLC is co-located with a Cluster Controller (CC), starting with HP Helion Eucalyptus 3.2.1, the firewall rules must be stored in /etc/eucalyptus/iptables-preload to be preserved across CC reboots. You must do a clean restart of the CC after adding firewall rules to that file (in HA mode, a clean stop/start is needed for primary and secondary CCs).


HP Helion Eucalyptus 3.3.0 resolves this issue by upgrading to PostgreSQL 9.1.9.

Please see https://www.eucalyptus.com/download/eucalyptus for instructions on downloading and upgrading to the latest HP Helion Eucalyptus software.


It was determined that upgrades to HP Helion Eucalyptus 3.3.0 packages did not always enforce the PostgreSQL 9.1.9 package to be installed. The eucalyptus-cloud package version 3.3.0-0.0.1140 or greater resolves this issue.
