Severity Level: 
Issue Date: 
Last Updated: 
Affected Products: 
HP Helion Eucalyptus 3.0.2, 3.1.0 and earlier


A security vulnerability has been identified in the configuration of the Apache Santuario (XML Security for Java) library used by HP Helion Eucalyptus 3.1.0 and earlier. An update is now available that resolves this issue. We advise immediately updating all affected HP Helion Eucalyptus installations following the instructions below.


HP Helion Eucalyptus Java-based components use the Apache Santuario (XML Security) library for processing digital signatures in SOAP requests. The provided library configuration allowed for the use of XML Signature transforms (such as XSL-T and XPath) that could be abused by a malicious user and lead to Denial of Service attacks.


HP Helion Eucalyptus versions 3.1.1 resolves this issue.
