Debian Security Advisory DSA-4570-1 [email protected]

Package : mosquitto
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.
For the detailed security status of mosquitto please refer to its
security tracker page at:
https://security-tracker.debian.org/tracker/mosquitto
