CVE-2017-7654 Due to a memory leak unauthenticated clients can send special crafted CONNECT packets which could cause a denial of service in the broker. CVE-2017-9868 Due to wrong file permissions local users could obtain topic information from the mosquitto database. For Debian 8 "Jessie", these problems have been fixed in version 1.3.4-2+deb8u3.
