Announcement ID: openSUSE-SU-2014:1493-1 Rating: moderate References: #898917 Cross-References: CVE-2014-7202 CVE-2014-7203 Affected Products: openSUSE 13.2 ______________________________________________________________________________
An update that fixes two vulnerabilities is now available.
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://.
