"description": "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\nIn Mosquitto before 2.0.16, a memory leak occurs when clients send v5 CONNECT packets with a will message that contains invalid property types.\n(CVE-2023-3592)\r\n\r\nIn Eclipse Mosquito before and including 2.0.5, establishing a connection to the mosquitto server without sending data causes the EPOLLOUT event to be added, which results excessive CPU consumption. This could be used by a malicious actor to perform denial of service type attack. This issue is fixed in 2.0.6\r\n\r\n\n(CVE-2023-5632)",
