A denial-of-service issue was discovered in the MQTT library in Arm Mbed OS 2017-11-02. The function readMQTTLenString() is called by the function MQTTDeserialize_publish() to get the length and content of the MQTT topic name. In the function readMQTTLenString(), mqttstring->lenstring.len is a part of user input, which can be manipulated. An attacker can simply change it to a larger value to invalidate the if statement so that the statements inside the if statement are skipped, letting the value of mqttstring->lenstring.data default to zero. Later, curn is accessed, which points to mqttstring->lenstring.data. On an Arm Cortex-M chip, the value at address 0x0 is actually the initialization value for the MSP register. It is highly dependent on the actual firmware. Therefore, the behavior of the program is unpredictable from this time on.

A vulnerability in the Cisco Fabric Services component of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a buffer overflow, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient validation of Cisco Fabric Services packets.

The packet is in an incorrect format and cannot be decoded by the node correctly. As a result, the node may consume the memory sustainably and crash. More details are shown at: https://github.com/FISCO-BCOS/FISCO-BCOS/issues/1951

ICMP redirect messages may crash or lock up a host.

MDaemon Email Server 19 through 20.0.1 skips SpamAssassin checks by default for e-mail messages larger than 2 MB (and limits checks to 10 MB even with special configuration), which is arguably inconsistent with currently popular message sizes. This might interfere with risk management for malicious e-mail, if a customer deploys a server with sufficient resources to scan large messages.
