data.

The vulnerability is caused due to an error in the TLS protocol while

arbitrary plaintext before data sent by a legitimate client in an
existing TLS session via Man-in-the-Middle (MitM) attacks.

This is related to:
SA37291

SOLUTION:
Reportedly, a fixed is planned for Access Manager 3.1 SP3, targeted
for Q4 2010.
