A flaw was found in dom4j library. By using the default SaxReader() provided by Dom4J, external DTDs and External Entities are allowed, resulting in a possible XXE.

For Debian 8 ‘Jessie’, this problem has been fixed in version 1.6.1+dfsg.3-2+deb8u2.

We recommend that you upgrade your dom4j 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.
