    CVE ID         : CVE-2019-11779
    Debian Bug     : 940654
    
    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.
