Threats affecting pkg:github/nanomq/nanomq

NanoMQ v0.22.7 is vulnerable to Denial of Service (DoS) due to improper resource throttling. A crafted sequence of requests causes the recv-q queue to saturate, leading to the rapid exhaustion of system file descriptors (FDs). This exhaustion triggers a process crash, rendering the broker unable to provide services.

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

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.

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.

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.

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