Blackhat removed the video from David Litchfield (containing the 0day exploit code for 11g) from their website. But it’s too late because the 0day code for 11g can be found in the meantime in many places.
The video was downloaded several times and it’s just a question of time until it re-appears…
BTW Oracle 10.2.0.4 with all security patches is vulnerable against this issue too. But the exploit must be modified a little bit.
