<p>Groovy’s MethodClosure class, in runtime/MethodClosure.java, is

|

vulnerable to a crafted serialized object.

<p>Remote attackers could potentially execute arbitrary code, or cause

Denial of Service condition

<workaround>
|
|
|
|
|
|
<p>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.
