  Log Message:
  zeromq: updated to 4.3.4

  New DRAFT (see NEWS for 4.2.0) socket option:

  ZMQ_PRIORITY will set the SO_PRIORITY socket option on the underlying
  sockets. Only supported on Linux.
  See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
  Fixed 4113 - compilation errors on kFreeBSD and GNU/Hurd

  directory

  Security advisories:

  CVE-2020-15166: Denial-of-Service on CURVE/ZAP-protected servers by
  unauthenticated clients.
  If a raw TCP socket is opened and connected to an endpoint that is fully
  configured with CURVE/ZAP, legitimate clients will not be able to exchange
  any message. Handshakes complete successfully, and messages are delivered to
  the library, but the server application never receives them.
  For more information see the security advisory:
  GHSA-25wp-cf8g-938m
  Stack overflow on server running PUB/XPUB socket (CURVE disabled).
  The PUB/XPUB subscription store (mtrie) is traversed using recursive
  function calls. In the remove (unsubscription) case, the recursive calls are
  NOT tail calls, so even with optimizations the stack grows linearly with the
  length of a subscription topic. Topics are under the control of remote
  clients - they can send a subscription to arbitrary length topics. An
  attacker can thus cause a server to create an mtrie sufficiently large such
  that, when unsubscribing, traversal will cause a stack overflow.
  For more information see the security advisory:
  GHSA-qq65-x72m-9wr8
  Memory leak in PUB server induced by malicious client(s) without CURVE/ZAP.
  Messages with metadata are never processed by PUB sockets, but the metadata
  is kept referenced in the PUB object and never freed.
  For more information see the security advisory:
  GHSA-4p5v-h92w-6wxw
  Memory leak in client induced by malicious server(s) without CURVE/ZAP.
  When a pipe processes a delimiter and is already not in active state but
  still has an unfinished message, the message is leaked.
  For more information see the security advisory:
  GHSA-wfr2-29gj-5w87
  Heap overflow when receiving malformed ZMTP v1 packets (CURVE disabled).
  By crafting a packet which is not valid ZMTP v2/v3, and which has two
  messages larger than 8192 bytes, the decoder can be tricked into changing
  the recorded size of the 8192 bytes static buffer, which then gets overflown
  by the next message. The content that gets written in the overflown memory
  is entirely decided by the sender.
  For more information see the security advisory:
  GHSA-fc3w-qxf5-7hp6
  Note for packagers: an external, self-contained sha1 library is now
  included in the source tree under external/sha1/ - it is licensed
  under BSD-3-Clause and thus it is fully compatible with libzmq's
  license.
  It is only used if WebSockets support is enabled, and if neither GnuTLS nor
  NSS are available.

  Note for packagers: an internal reimplementation of strlcpy is now included,
  for wider platform compatibility.
  libbsd can be used and is enabled by default if available instead of the
  internal implementation, for better security maintenance in distros.

  Note for packagers: ZeroMQConfig.cmake is now installed in the arch-dependent
  subdirectory - eg: /usr/lib/x86_64-linux-gnu/cmake/

  New DRAFT (see NEWS for 4.2.0) socket type:

  ZMQ_CHANNEL is a thread-safe alternative to ZMQ_PAIR.
  See doc/zmq_socket.txt for details.
  New DRAFT (see NEWS for 4.2.0) socket option:

  ZMQ_ONLY_FIRST_SUBSCRIBE will cause only the first part of a multipart
  message to be processed as a subscribe/unsubscribe message, and the rest
  will be forwarded as user data to the application.
  ZMQ_RECONNECT_STOP will cause a connecting socket to stop trying to
  reconnect in specific circumstances. See the manpage for details.
  ZMQ_HELLO_MSG to set a message that will be automatically sent to a new
  connection.
  ZMQ_DISCONNECT_MSG to set a message that will be automatically received when
  a peer disconnects.
  See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
  New DRAFT (see NEWS for 4.2.0) zmq_ctx_get_ext/zmq_ctx_set_ext APIs were added
  to allow enhancing the context options with variable data inputs.
  See doc/zmq_ctx_get_ext.txt and doc/zmq_ctx_set_ext.txt for details.

  New DRAFT (see NEWS for 4.2.0) transport options WS and WSS added for support
  of WebSockets (and secure WebSockets via TLS) via the ZWS 2.0 protocol.
  WSS requires the GnuTLS library for TLS support. ZMQ_WSS_ specific socket
  options were added to support TLS.
  WebSockets support is disabled by default if DRAFT APIs are disabled.

  New DRAFT (see NEWS for 4.2.0) socket type, PEER, which is thread safe and a
  related zmq_connect_peer function which atomically and thread-safely connects
  and returns a routing-id.

  New DRAFT (see NEWS for 4.2.0) zmq_msg_init_buffer API was added to allow
  the construction of a message by copying from an existing buffer.

  New DRAFT (see NEWS for 4.2.0) zmq_poller_size API was added to allow querying
  the number of sockets/fds registered in a zmq_poller.

  ZMTP 3.1 peers will receive subscribe/cancel on PUB/SUB via commands rather
  than using the first byte of the payload.

  zmq_z85_decode now checks that the input string's length is at least 5
  characters
  and always a multiple of 5 as per API specification.
