Synopsis
========
Groovy is vulnerable to a remote execution of arbitrary code when java
serialization is used.

Background
==========
A multi-faceted language for the Java platform

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-java/groovy < 2.4.5 >= 2.4.5

Description
===========
Groovy's MethodClosure class, in runtime/MethodClosure.java, is
vulnerable to a crafted serialized object.

Impact
======
Remote attackers could potentially execute arbitrary code, or cause
Denial of Service condition

Workaround
==========
A workaround exists by using a custom security policy file utilizing
the standard Java security manager, or do not rely on serialization to
communicate remotely.

Resolution
==========
All Groovy users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/groovy-2.4.5"

References
==========
