Unspecified vulnerability in the OracleVM component in Oracle VM 2.2.1 allows remote authenticated users to affect confidentiality, integrity, and availability via unknown vectors related to ovs-agent. NOTE: the previous information was obtained from the October 2010 CPU. Oracle has not commented on claims from a third party researcher that this is related to the exposure of multiple unspecified functions through XML-RPC that allow execution of arbitrary OS commands.
