DESCRIPTION:
Cisco has acknowledged a vulnerability in multiple Cisco products,
which can be exploited by malicious people to manipulate certain
data.

The vulnerability is caused due to an error in the TLS protocol while
handling session renegotiations. This can be exploited to insert
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
