==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS
Summary:
An attacker could send crafted input to Eucalyptus to run commands as
a valid user.
Software Description:
- eucalyptus: Elastic Utility Computing Architecture
- rampart: Apache web services security engine
Details:
Juraj Somorovsky, Jorg Schwenk, Meiko Jensen and Xiaofeng Lou discovered
that Eucalyptus did not properly validate SOAP requests. An unauthenticated
remote attacker could exploit this to submit arbitrary commands to the
Eucalyptus SOAP interface in the context of an authenticated user.
