"This udpate for zeromq fixes the following non-security and
security-issues: Update to version 4.0.4, for a detailed description
see /usr/share/doc/packages/zeromq-devel/NEWS

  - Add libsodium dep for testsuite where possible

  - Version bump to 4.0.5 fixes bnc#898917 CVE-2014-7202 and
    CVE-2014-7203 :

  - Fixed CURVE mechanism does not verify short term nonces.

  - Fixed stream_engine is vulnerable to downgrade attacks.

  - Fixed assertion failure for WSAENOTSOCK on Windows.

  - Fixed race condition while connecting inproc sockets.

  - Fixed bump so library number to 4.0.0

  - Fixed assertion failed: !more (fq.cpp:99) after many ZAP
    requests.

  - Fixed lost first part of message over inproc://.

  - Fixed keep-alive on Windows.

  - Enable tests.

  - Move to 'download_files' source service which is in
    better shap and easier to use"

"zeromq was updated to version 4.0.5 to fix two security issues and
various other bugs.

These security issues were fixed :

  - Did not validate the other party's security handshake
    properly, allowing a man-in-the-middle downgrade attack
    (CVE-2014-7202).

  - Did not implement a uniqueness check on connection
    nonces, and the CurveZMQ RFC was ambiguous about nonce
    validation. This allowed replay attacks (CVE-2014-7203).

Other issues fixed in this update :

  - CURVE mechanism does not verify short term nonces.

  - stream_engine is vulnerable to downgrade attacks.

  - assertion failure for WSAENOTSOCK on Windows.

  - race condition while connecting inproc sockets.

  - bump so library number to 4.0.0

  - assertion failed: !more (fq.cpp:99) after many ZAP
    requests.

  - lost first part of message over inproc://."
