vulnerability in libxstream-java, a Java library to serialize objects

an instance of the primitive type 'void' during unmarshalling.

For Debian 7 'Wheezy', this issue has been fixed in libxstream-java
version 1.4.2-1+deb7u2.

We recommend that you upgrade your libxstream-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."
