{"id":"OESA-2023-1680","summary":"mosquitto security update","details":"Mosquitto is an open source message broker that implements the MQ Telemetry Transport protocol version 3.1 and 3.1.1 MQTT provides a lightweight method of carrying out messaging using a publish/subscribe model. This makes it suitable for "machine to machine" messaging such as with low power sensors or mobile devices such as phones, embedded computers or micro-controllers like the Arduino.\r\n\r\nSecurity Fix(es):\r\n\r\nThe broker in Eclipse Mosquitto 1.3.2 through 2.x before 2.0.16 has a memory leak that can be abused remotely when a client sends many QoS 2 messages with duplicate message IDs, and fails to respond to PUBREC commands. This occurs because of mishandling of EAGAIN from the libc send function.(CVE-2023-28366)","modified":"2025-09-03T06:19:05.279612Z","published":"2023-09-22T11:06:00Z","upstream":["CVE-2023-28366"],"database_specific":{"severity":"High"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/en/security/safety-bulletin/detail.html?id=openEuler-SA-2023-1680"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-28366"}],"affected":[{"package":{"name":"mosquitto","ecosystem":"openEuler:22.03-LTS","purl":"pkg:rpm/openEuler/mosquitto&distro=openEuler-22.03-LTS"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.0.16-1.oe2203"}]}],"ecosystem_specific":{"src":["mosquitto-2.0.16-1.oe2203.src.rpm"],"x86_64":["mosquitto-debuginfo-2.0.16-1.oe2203.x86_64.rpm","mosquitto-devel-2.0.16-1.oe2203.x86_64.rpm","mosquitto-2.0.16-1.oe2203.x86_64.rpm","mosquitto-debugsource-2.0.16-1.oe2203.x86_64.rpm"],"aarch64":["mosquitto-debuginfo-2.0.16-1.oe2203.aarch64.rpm","mosquitto-2.0.16-1.oe2203.aarch64.rpm","mosquitto-devel-2.0.16-1.oe2203.aarch64.rpm","mosquitto-debugsource-2.0.16-1.oe2203.aarch64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2023-1680.json"}}],"schema_version":"1.7.3"}
