Alex has today released a paper on how to bypass the fix that Oracle has created for a lot of SQL Injection vulnerabilities fixed in recent CPU's. Oracle has used a package DBMS_ASSERT to stop SQL Injection. Alex has detailed in his paper "Bypassing Oracle DBMS_ASSERT" how to bypass this package and make a good proportion of the bugs fixed in previous CPU's exploitable again.
The interesting point in the paper is that Oracle didnt have an issue with Alex publishing this paper and revealing the issues. Why?
