Debian DLA-2616-1 : libxstream-java security update

critical Nessus Plugin ID 148312


The remote Debian host is missing a security update.


In XStream there is a vulnerability which may allow a remote attacker to load and execute arbitrary code from a remote host only by manipulating the processed input stream.

The type hierarchies for, java.nio.channels.Channel, javax.activation.DataSource and javax.sql.rowsel.BaseRowSet are now blacklisted as well as the individual types,$NameProcessI terator, sun.awt.datatransfer.DataTransferer$IndexOrderComparator, and sun.swing.SwingLazyValue. Additionally the internal type Accessor$GetterSetterReflection of JAXB, the internal types MethodGetter$PrivilegedGetter and ServiceFinder$ServiceNameIterator of JAX-WS, all inner classes of javafx.collections.ObservableList and an internal ClassLoader used in a private BCEL copy are now part of the default blacklist and the deserialization of XML containing one of the types will fail. You will have to enable these types by explicit configuration, if you need them.

For Debian 9 stretch, these problems have been fixed in version

We recommend that you upgrade your libxstream-java packages.

For the detailed security status of libxstream-java please refer to its security tracker page at:

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.


Upgrade the affected libxstream-java package.
