c3p0: loading XML configuration leads to denial of service

CVE-2019-5427 [HIGH] CWE-776 c3p0: loading XML configuration leads to denial of service
c3p0: loading XML configuration leads to denial of service
c3p0 version < 0.9.5.4 may be exploited by a billion laughs attack when loading XML configuration due to missing protections against recursive entity expansion when loading configuration.
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.
