Alvaro Munoz and Christian Schneider discovered that Jython, an implementation of the Python language seamlessly integrated with Java, would execute arbitrary code when deserializing objects.

For Debian 7 ‘Wheezy’, these problems have been fixed in version 2.5.2-1+deb7u1.

We recommend that you upgrade your jython 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.
