Currently, there are no known vulnerabilities with ECDHE cipher suites. We plan to add a feature to allow customer's to select cipher suites they would like to support in 8.2RX. This is planned for the later part of Q4 2015.
A new feature to disable 1024 bit DH key exchange will be added in new releases of code. Please see the "Logjam" section on the following security advisory for more information: https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA40002
Correct. There is no current way to specifically disable all ECDHE and DHE cipher suites. However, due to the recent concerns with 1024-bit DHE cipher suites and below, we will be making a change to disable 1024-bit DHE cipher in the next releases.
