Detail
A vulnerability was discovered in mosquitto, a MQTT version 3.1/3.1.1 compatible message broker, allowing a malicious MQTT client to cause a denial of service (stack overflow and daemon crash), by sending a specially crafted SUBSCRIBE packet containing a topic with a extremely deep hierarchy. For the stable distribution (buster), this problem has been fixed in version 1.5.7-1+deb10u1. We recommend that you upgrade your mosquitto packages. For the detailed security status of mosquitto please refer to its security tracker page at: https://security-tracker.debian.org/tracker/mosquitto |
