Buffer Overflow vulnerability in the get_var_integer function in mqtt_parser.c in NanoMQ 0.21.7 allows remote attackers to cause a denial of service via a series of specially crafted hexstreams.

Null Pointer Dereference vulnerability in topic_filtern function in mqtt_parser.c in NanoMQ 0.21.7 allows attackers to cause a denial of service.

A heap-buffer-overflow vulnerability in the read_byte function in NanoMQ v.0.21.7 allows attackers to cause a denial of service via transmission of crafted hexstreams.

nanomq 0.21.2 contains a Use-After-Free vulnerability in /nanomq/nng/src/core/socket.c.

In NanoMQ v0.15.0-0, segment fault with Null Pointer Dereference occurs in the process of decoding subinfo_decode and unsubinfo_decode.

In NanoMQ v0.15.0-0, a Heap overflow occurs in copyn_utf8_str function of mqtt_parser.c

In NanoMQ v0.15.0-0, Heap overflow occurs in read_byte function of mqtt_code.c.

A memory leak vulnerability exists in NanoMQ 0.17.2. The vulnerability is located in the file message.c. An attacker could exploit this vulnerability to cause a denial of service attack by causing the program to consume all available memory resources.

A heap buffer overflow vulnerability exists in NanoMQ 0.17.2. The vulnerability can be triggered by calling the function nmq_subinfo_decode() in the file mqtt_parser.c. An attacker could exploit this vulnerability to cause a denial of service attack.

A heap buffer overflow vulnerability exists in NanoMQ 0.17.2. The vulnerability can be triggered by calling the function copyn_str() in the file mqtt_parser.c. An attacker could exploit this vulnerability to cause a denial of service attack.

A heap buffer overflow vulnerability exists in NanoMQ 0.17.2. The vulnerability can be triggered by calling the function nni_msg_get_pub_pid() in the file message.c. An attacker could exploit this vulnerability to cause a denial of service attack.

A use-after-free vulnerability exists in NanoMQ 0.17.2. The vulnerability can be triggered by calling the function nni_mqtt_msg_get_publish_property() in the file mqtt_msg.c. This vulnerability is caused by improper data tracing, and an attacker could exploit it to cause a denial of service attack.

NanoMQ 0.16.5 is vulnerable to heap-use-after-free in the nano_ctx_send function of nmq_mqtt.c.

An invalid read size in Nanomq v0.21.9 allows attackers to cause a Denial of Service (DoS).
