CVE-2017-1000385 + + Exploiting this vulnerability to perform plaintext + recovery of encrypted messages will, in most practical + cases, allow an attacker to read the plaintext only + after the session has completed. Only TLS sessions + established using RSA key exchange are vulnerable to + this attack. + + Exploiting this vulnerability to conduct a MiTM attack + requires the attacker to complete the initial attack, + which may require thousands of server requests, during + the handshake phase of the targeted session within the + window of the configured handshake timeout. This attack + may be conducted against any TLS session using RSA + signatures, but only if cipher suites using RSA key + exchange are also enabled on the server.

moving more code to Erlang from the old linked-in + driver and implementing all the I/O primitives needed + in a NIF instead. + + On Unix platforms the user should not notice a lot of + difference, besides better handling of unicode + characters and fixing of some long standing bugs. + + Windows users will notice that erl.exe has the same + functionality as a normal Unix shell and that werl.exe + has been removed and replaced with a symlink to + erl.exe. This makes the Windows Erlang terminal + experience identical to that of Unix. + + The re-write brings with it a number of bug fixes and + feature additions: + + -- The TTY is now reset when Erlang exits, fixing zsh + to not break when terminating an Erlang session. + + -- standard_error now uses the same unicode mode as + standard_io. + + -- Hitting backspace when searching the shell history + with an empty search string no longer breaks the shell. + + -- Tab expansion now works on remote nodes started + using the JCL interface. + + -- It is now possible to configure the shell slogan and + the session slogans (that is the texts that appear when + you start an Erlang shell).
