EUVD-2026-36663

LiamBindle MQTT-C through version 1.1.6 contains a heap-based out-of-bounds read and integer underflow in the mqttunpackpublishresponse function in src/mqtt.c that allows a remote unauthenticated attacker controlling an MQTT broker - or able to inject MQTT traffic into an unencrypted session - to...

curl: integer Overflow in MQTT Protocol Handling Allows Bypassing Message Size Limit

Summary: A logic error involving an integer overflow specifically, an unsigned integer underflow exists in the lib/mqtt.c file within the mqttpublish function. This vulnerability allows an attacker or a malicious user configuration to bypass the explicit MAXMQTTMESSAGESIZE check. The vulnerabilit...

curl: libcurl MQTT PUBLISH length overflow (heap overflow)

Summary: Heap-based buffer overflow in libcurl’s MQTT PUBLISH assembly lib/mqtt.c::mqttpublish due to unchecked sizet arithmetic when computing the MQTT “Remaining Length”. If payloadlen + 2 + topiclen wraps sizet, libcurl allocates a too-small buffer and then memcpy’s payloadlen bytes into it,...

CVE-2019-13120

Amazon FreeRTOS up to and including v1.4.8 lacks length checking in prvProcessReceivedPublish, resulting in untargetable leakage of arbitrary memory contents on a device to an attacker. If an attacker has the authorization to send a malformed MQTT publish packet to an Amazon IoT Thing, which...

DEBIAN-CVE-2023-2905

Due to a failure in validating the length of a provided MQTTCMDPUBLISH parsed message with a variable length header, Cesanta Mongoose, an embeddable web server, version 7.10 is susceptible to a heap-based buffer overflow vulnerability in the default configuration. Version 7.9 and prior does not...
