"A XML External Entity (XXE) vulnerability was discovered in c3p0, a
library for JDBC connection pooling, that may be used to resolve
information outside of the intended sphere of control.

For Debian 8 'Jessie', this problem has been fixed in version
0.9.1.2-9+deb8u1.

We recommend that you upgrade your c3p0 packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
