Package : mosquitto Version : 2.0.11-1+deb11u2 CVE ID : CVE-2024-3935 CVE-2024-10525

The following vulnerabilities have been discovered in the package mosquitto, MQTT message broker.

CVE-2024-3935

If a Mosquitto broker is configured to create an outgoing bridge connection, and that bridge connection has an incoming topic configured that makes use of topic remapping, then if the remote connection sends a crafted PUBLISH packet to the broker a double free will occur with a subsequent crash of the broker.

CVE-2024-10525

If a malicious broker sends a crafted SUBACK packet with no reason codes, a client using libmosquitto may make out of bounds memory access when acting in its on_subscribe callback. This affects the mosquitto_sub and mosquitto_rr clients.

For Debian 11 bullseye, these problems have been fixed in version 2.0.11-1+deb11u2.

We recommend that you upgrade your mosquitto packages.
