    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.
