| CVE-2017-7655 | 2 Debian, Eclipse | 2 Debian Linux, Mosquitto | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| In Eclipse Mosquitto version from 1.0 to 1.4.15, a Null Dereference vulnerability was found in the Mosquitto library which could lead to crashes for those applications using the library. | |||||
| CVE-2017-7654 | 2 Debian, Eclipse | 2 Debian Linux, Mosquitto | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| In Eclipse Mosquitto 1.4.15 and earlier, a Memory Leak vulnerability was found within the Mosquitto Broker. Unauthenticated clients can send crafted CONNECT packets which could cause a denial of service in the Mosquitto Broker. | |||||
| CVE-2017-7653 | 2 Debian, Eclipse | 2 Debian Linux, Mosquitto | 2026-06-17 | 3.5 LOW | 5.3 MEDIUM |
| The Eclipse Mosquitto broker up to version 1.4.15 does not reject strings that are not valid UTF-8. A malicious client could cause other clients that do reject invalid UTF-8 strings to disconnect themselves from the broker by sending a topic string which is not valid UTF-8, and so cause a denial of service for the clients. | |||||
| CVE-2017-7652 | 2 Debian, Eclipse | 2 Debian Linux, Mosquitto | 2026-06-17 | 6.0 MEDIUM | 7.5 HIGH |
| In Eclipse Mosquitto 1.4.14, if a Mosquitto instance is set running with a configuration file, then sending a HUP signal to server triggers the configuration to be reloaded from disk. If there are lots of clients connected so that there are no more file descriptors/sockets available (default limit typically 1024 file descriptors on Linux), then opening the configuration file will fail. | |||||
| CVE-2017-7651 | 2 Debian, Eclipse | 2 Debian Linux, Mosquitto | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| In Eclipse Mosquitto 1.4.14, a user can shutdown the Mosquitto server simply by filling the RAM memory with a lot of connections with large payload. This can be done without authentications if occur in connection phase of MQTT protocol. | |||||
| CVE-2017-7650 | 2 Debian, Eclipse | 2 Debian Linux, Mosquitto | 2026-06-17 | 4.0 MEDIUM | 6.5 MEDIUM |
| In Mosquitto before 1.4.12, pattern based ACLs can be bypassed by clients that set their username/client id to '#' or '+'. This allows locally or remotely connected clients to access MQTT topics that they do have the rights to. The same issue may be present in third party authentication/access control plugins for Mosquitto. | |||||
