The Pulse Secure products, listed above, have resolved CVE-2009-3555, in accordance with IETF standards.

CVE-2009-3555 summary: The TLS protocol, and the SSL protocol 3.0 and possibly earlier, does not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions, and possibly other types of sessions protected by TLS or SSL, by sending an unauthenticated request that is processed retroactively by a server in a post-renegotiation context, related to a "plaintext injection" attack, aka the "Project Mogul" issue. (Note: US-CERT identifies this issue as VU#120541.)

Any workarounds published by Pulse Secure are still valid however upgrade is recommended.
