An update for mosquitto is now available for openEuler-22.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2023-1772 Final 1.0 1.0 2023-10-28 Initial 2023-10-28 2023-10-28 openEuler SA Tool V1.0 2023-10-28 mosquitto security update An update for mosquitto is now available for openEuler-22.03-LTS. 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. Security Fix(es): In Mosquitto before 2.0.16, a memory leak occurs when clients send v5 CONNECT packets with a will message that contains invalid property types. (CVE-2023-3592) In 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 (CVE-2023-5632) An update for mosquitto is now available for openEuler-22.03-LTS. openEuler Security has rated this update as having a security impact of high.
