A flaw was found in the ZeroMQ server in versions before 4.3.3. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Buffer Copy without Size Check vulnerability could allow attackers to overflow a buffer to corrupt adjacent memory.
libzmq before 4.0.6 and 4.1.x before 4.1.1 allows remote attackers to conduct downgrade attacks and bypass ZMTP v3 protocol security mechanisms via a ZMTP v2 or earlier header. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable. No vendor patch available.
libzmq (aka ZeroMQ/C++) 4.0.x before 4.0.5 does not ensure that nonces are unique, which allows man-in-the-middle attackers to conduct replay attacks via unspecified vectors. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable. No vendor patch available.
stream_engine.cpp in libzmq (aka ZeroMQ/C++)) 4.0.5 before 4.0.5 allows man-in-the-middle attackers to conduct downgrade attacks via a crafted connection request. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable. No vendor patch available.
