On Wednesday, May 20th, 2015 the Security team at Blue Jeans Network became aware of the latest vulnerability in TLS protocol named "Logjam" or the Weak/EXPORT Diffie-Hellman Man-in-the-middel vulnerability.

This new vulnerability is similar to another recent announcement regarding SSL and TLS and Blue Jeans Network already disabled all "EXPORT" grade cipher suites and is not vulnerable to Logjam or FREAK because of these efforts. In our production environment, we support a minimum of 2048-bit keys for asymmetric encryption, and 128-bit key for symmetric encryption, this applies to Diffie-Hellman key exchanges as well.

The security team at Blue Jeans Network is striving for continuous improvement and staying ahead of these efforts.

If you want to learn more about the vulnerability, information is available at https://weakdh.org/ including the research paper which discloses it.

If you have further questions, you may contact Technical Support, your Customer Success Manager, or your account representative.

Sincerely,
Security @ Blue Jeans Network
