| CVE-2019-6250 | Hig | 0.58 | 8.8 | 0.09 | Jan 13, 2019 | A pointer overflow, with code execution, was discovered in ZeroMQ libzmq (aka 0MQ) 4.2.x and 4.3.x before 4.3.1. A v2_decoder.cpp zmq::v2_decoder_t::size_ready integer overflow allows an authenticated attacker to overwrite an arbitrary amount of bytes beyond the bounds of a… | ||
| CVE-2021-20236 | Cri | 0.57 | 9.8 | 0.02 | May 28, 2021 | A flaw was found in the ZeroMQ server in versions before 4.3.3. This flaw allows a malicious client to cause a stack buffer overflow on the server by sending crafted topic subscription requests and then unsubscribing. The highest threat from this vulnerability is to… | ||
| CVE-2021-20235 | Hig | 0.49 | 8.1 | 0.44 | Apr 1, 2021 | There's a flaw in the zeromq server in versions before 4.3.3 in src/decoder_allocators.hpp. The decoder static allocator could have its sized changed, but the buffer would remain the same as it is a static buffer. A remote, unauthenticated attacker who sends a crafted request to… | ||
| CVE-2021-20237 | Hig | 0.42 | 7.5 | 0.02 | May 28, 2021 | An uncontrolled resource consumption (memory leak) flaw was found in ZeroMQ's src/xpub.cpp in versions before 4.3.3. This flaw allows a remote unauthenticated attacker to send crafted PUB messages that consume excessive memory if the CURVE/ZAP authentication is disabled on the… | ||
| CVE-2021-20234 | Med | 0.35 | 6.5 | 0.01 | Apr 1, 2021 | An uncontrolled resource consumption (memory leak) flaw was found in the ZeroMQ client in versions before 4.3.3 in src/pipe.cpp. This issue causes a client that connects to multiple malicious or compromised servers to crash. The highest threat from this vulnerability is to… | ||
| CVE-2020-15166 | Hig | 0.00 | 7.5 | 0.03 | Sep 11, 2020 | In ZeroMQ before version 4.3.3, there is a denial-of-service vulnerability. Users with TCP transport public endpoints, even with CURVE/ZAP enabled, are impacted. If a raw TCP socket is opened and connected to an endpoint that is fully configured with CURVE/ZAP, legitimate… | ||
| CVE-2014-9721 | 0.00 | — | 0.03 | Jun 3, 2015 | 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. | |||
| CVE-2014-7203 | 0.00 | — | 0.02 | Oct 8, 2014 | 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. | |||
| CVE-2014-7202 | 0.00 | — | 0.02 | Oct 8, 2014 | 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. |
