"An untrusted deserialization was found in the
org.apache.xmlrpc.parser.XmlRpcResponseParser:addResult method of
Apache XML-RPC (aka ws-xmlrpc) library. A malicious XML-RPC server
could target a XML-RPC client causing it to execute arbitrary code.

Clients that expect to get server-side exceptions need to set the
enabledForExceptions property to true in order to process serialized
exception messages again.

For Debian 8 'Jessie', this problem has been fixed in version
3.1.3-7+deb8u1.

We recommend that you upgrade your libxmlrpc3-java 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."
