Description Josh Bressers 2010-10-12 14:44:51 UTC

Mozilla cryptographer Nelson Bolyard reported that the SSL implementation
was permitting servers to use 256-bit Diffie-Hellman Ephemeral mode (DHE)
for key exchanges. A DHE key of this length is trivially breakable on
modern hardware so SSL servers operating in this mode were providing very
little effective security for its clients.
