groovy - security update

cpnrodzc7, working with HP’s Zero Day Initiative, discovered that
Java applications using standard Java serialization mechanisms to
decode untrusted data, and that have Groovy on their classpath, can
be passed a serialized object that will cause the application to
execute arbitrary code.

For the oldoldstable distribution (squeeze), this problem has been
fixed in version 1.7.0-4+deb6u1.

For the oldstable distribution (wheezy) and stable distribution
(jessie), this problem will be fixed soon.
