Oracle DBMS_STANDARD security problem

["putosoft softputo" <hasecorp () hotmail com>]

Hello,
I have been found a security problem in the DBMS_STANDARD package. Anyone 
knowns any kind of workaround for this problem? You can't create a package 
called DBMS_STANDARD and rename the old one to any other name to create an 
envoltory so there is no way (I think) to solve it.
Any recomended workaround (except switching to PostgreSQL), please?
