Description Wade Mealing 2014-09-28 21:55:51 EDT

libzmq (ZeroMQ/C++) did not implement a uniqueness check on connection
nonces, and the CurveZMQ RFC was ambiguous about nonce validation.

This allows an attacker to use a replay attacks on zeroMQ connections.

Comment 1 Murray McAllister 2014-09-28 22:40:55 EDT

Upstream commit:

https://github.com/steamraven/libzmq/commit/0900a489213d74feb86fc0b343308fe7884a2a3c

From a brief inspection, it appears as though zeromq and zeromq 3 in Fedora may not be affected.

Comment 2 Wade Mealing 2014-09-29 04:53:18 EDT

In the version zeromq3-3.2.4-1.el6.src.rpm from EPEL, this -doesnt- even seem to mention the word nonce, or have any curve_client.cpp file, so I'm going to say that 1.2  its not effected by this issue, i'm not sure about 1.3

Comment 4 Wade Mealing 2014-10-07 20:27:28 EDT

Statement:

This issue did not affect the versions of zeromq as shipped with Inktank Ceph Enterprise 1.2 and 1.3.

Comment 5 Wade Mealing 2014-10-09 00:39:36 EDT

The fedora 20 release zeromq3-3.2.4-1.fc20.src.rpm ,is the same release that was audited by the inktank developers found to be not affected by this issue.
