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 clients will not be able to exchange any message. Handshakes complete successfully, and messages are delivered to the library, but the server application never receives them. This is patched in version 4.3.3.

CVE-2020-15166 [CRITICAL] ZeroMQ vulnerabilities
Title: ZeroMQ vulnerabilities
Summary: Several security issues were fixed in ZeroMQ.
It was discovered that ZeroMQ incorrectly handled certain application
metadata. A remote attacker could use this issue to cause ZeroMQ to crash,
or possibly execute arbitrary code. (CVE-2019-13132)
It was discovered that ZeroMQ mishandled certain network traffic. An
unauthenticated attacker could use this vulnerability to cause a denial-of-
service and prevent legitimate clients from communicating with ZeroMQ.
(CVE-2020-15166)
It was discovered that ZeroMQ did not properly manage memory under certain
circumstances. If a user or automated system were tricked into connecting
to one or multiple compromised servers, a remote attacker could use this
issue to cause a denial of service. (CVE-2021-20234)

CVE-2020-15166 [HIGH] CWE-400 zeromq: unauthenticated clients causing denial-of-service
zeromq: unauthenticated clients causing denial-of-service
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 clients will not be able to exchange any message. Handshakes complete successfully, and messages are delivered to the library, but the server application never receives them. This is patched in version 4.3.3.
A flaw was found in ZeroMQ, where the possibility of unauthenticated clients causes a denial of service that affects authenticated and encrypted clients. The highest threat from this vulnerability is to system availability.
