Debian LTS: Security Advisory for libxstream-java (DLA-2616-1)

The remote host is missing an update for the 'libxstream-java' package(s) announced via the DLA-2616-1 advisory.

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.io.InputStream, java.nio.channels.Channel, javax.activation.DataSource and javax.sql.rowsel.BaseRowSet are now blacklisted as well as the individual types com.sun.corba.se.impl.activation.ServerTableEntry, com.sun.tools.javac.processing.JavacProcessingEnvironment$NameProcessIterator, sun.awt.datatransfer.DataTransferer$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.

'libxstream-java' package(s) on Debian Linux.

Checks if a vulnerable package version is present on the target host.

For Debian 9 stretch, these problems have been fixed in version 1.4.11.1-1+deb9u2. We recommend that you upgrade your libxstream-java packages.
