Clients are thankful that they have applications, applications are thankful to their databases, database are thankful to their DBAs, and DBAs are thankful to clients.

Ever hear of Red Hat Enterprise Linux 6.0? It was released on November the 10th of 2010 . . just over a year ago. In the last couple of days Oracle released the latest version of MySQL Server (5.5.18). Along with the bug fixes, etc they released RPM packages that cover RH EL 6.

Finally. A year later.

Not one given to griping, but really..does it take that long to roll packages for the new version? There were no significant changes in the operating system..in fact the RH EL 5 packages worked on RHEL 6 from my (albeit) limited experience with the combination.

I don't jump onto new versions of operating systems as soon as they come out. I prefer to let others be my beta testers before I put something into production. However, waiting a year seems a bit extreme for this release.

Even so, it's out now so enjoy! Now we have no excuse for not deploying 5.5.

Summary

As part of GreenSQL’s Database security research,  we’ve been validating and extending coverage of known and unknown vulnerabilities in order to increase GreenSQL product security, at this post we will reveal a full working Prove of Concept for the CVE-2007-4517 vulnerability which executes arbitrary code.

The Exploit: PL/SQL/2007-4517 exploit is a PL/SQL procedure that exploits the CVE-2007-4517 vulnerability, also known as Oracle Database XDB.XDB_PITRIG_PKG.PITRIG_DROPMETADATA Procedure Multiple Argument Remote Overflow.

The vulnerability is caused due to a boundary error in the XDB.XDB_PITRIG_PKG.PITRIG_DROPMETADATA procedure when processing the OWNER and NAME arguments to create an SQL query.

This can be exploited to cause a buffer overflow by passing overly long OWNER and NAME arguments to the affected procedure.
