Subject: CVE Request: zeromq downgrade attack
[ CCing upstream mailing list ]
Hello,
From https://github.com/zeromq/libzmq/issues/1273 :
> It is easy to bypass the security mechanism in 4.1.0 and 4.0.5 by sending a
> ZMTP v2 or earlier header. The library accepts such connections without
> applying its security mechanism.
>
> Solution: if security is defined on a socket, reject all V2 and earlier
> connections, unconditionally.
A patch for the zeromq 4.0.x stable series is available at
https://github.com/zeromq/zeromq4-x/commit/b6e3e0f601e2c1ec1f3aac880ed6a3fe63043e51
AFAICT no CVE has been assigned (or requested) for this, and the issue has
been public since December of last year.
Could a CVE be assigned please?
Cheers
