"It was found that a flaw in Apache Groovy, a dynamic language for the
Java Virtual Machine, allows remote code execution wherever
deserialization occurs in the application. It is possible for an
attacker to craft a special serialized object that will execute code
directly when deserialized. All applications which rely on
serialization and do not isolate the code which deserializes objects
are subject to this vulnerability.

For Debian 7 'Wheezy', these problems have been fixed in version
1.8.6-1+deb7u2.

We recommend that you upgrade your groovy 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."
