Remediation
Red Hat statement
Red Hat Satellite 6 is not vulnerable to this issue, because the candlepin component who uses the c3p0 jar never passes a XML configuration file to c3p0, even though it includes a vulnerable version of the latter. Since this issue requires a XML files to be loaded by c3p0, an exploitation path doesn't exist.
