Recently a security vulnerability named "Logjam" - CVE-2015-4000, was discovered which affects Diffie-Hellman algorithms (DHE_EXPORT) used in TLS negotiation.
The vulnerability allows a Man-in-the-Middle (MitM) attacker to trick the Client and Server into using legacy cipher parameters which are very easy to decrypt with brute force. Both the Client (usually a Browser) and the Server need to be vulnerable for this attack to work. Most browsers should already have updates available.
KEMP has determined that all LoadMasters are not affected as we do not support DHE_EXPORT cipher suites.
