zeromq3 vulnerabilities

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)

It was discovered that ZeroMQ incorrectly handled memory when processing messages with arbitrarily large sizes under certain circumstances. A remote unauthenticated attacker could use this issue to cause a ZeroMQ server to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 18.04 ESM and Ubuntu 20.04 ESM. (CVE-2021-20235)
