HP Helion Eucalyptus Security Advisory
Advisory ID: 
Severity Level: 
Issue Date: 
Last Updated: 
Affected Products: 
HP Helion Eucalyptus 2.0 to HP Helion Eucalyptus 3.4.1


A security issue has been identified in the way HP Helion Eucalyptus Java-based components handle network connections to web services APIs. All versions of HP Helion Eucalyptus starting from 2.0 are affected. An update is now available in 3.4.2 that resolves this issue. We advise immediately updating all affected HP Helion Eucalyptus installations.


A flaw was identified in the network connection clean up code that allows for Denial of Service attacks against HP Helion Eucalyptus web services APIs by remote, unauthenticated attackers. All Java-based components are affected, including Cloud Controller (CLC), Walrus, Storage Controller (SC), and VMware Broker (VB).


Restricting network access to HP Helion Eucalyptus web services APIs to trusted clients only (if possible) can help preventing intentional DoS attacks. Please refer the Administration Guide at https://www.eucalyptus.com/docs for HP Helion Eucalyptus open ports and connectivity rules.


HP Helion Eucalyptus 3.4.2 resolves this issue.
