openSUSE Security Update : zeromq (openSUSE-SU-2014:1493-1)

This script is Copyright (C) 2014 Tenable Network Security, Inc.


Synopsis :

The remote openSUSE host is missing a security update.

Description :

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://.
