Flaws impacting millions of internet of things devices running NVIDIA's Jetson chips open the door for a variety of hacks, including denial-of-service attacks or the siphoning of data. NVIDIA released patches addressing nine high-severity vulnerabilities including eight additional bugs of less severity.
Organizations have been warned about denial of service vulnerabilities found in RabbitMQ, EMQ X and VerneMQ, three widely used open source message brokers. Message brokers enable applications, systems and services to communicate with each other and exchange information by translating messages between formal messaging protocols.
Synopsys Cybersecurity Research Centre has warned of easily triggered denial-of-service vulnerabilities in three popular open-source Internet of Things message brokers: RabbitMQ, EMQ X, and VerneMQ. The message brokers, responsible for handling data sent to or from IoT devices like smart home hubs and door locks, all share a common protocol: Message Queuing Telemetry Transport, first released in 1999 for monitoring oil pipelines and since repurposed for a variety of home and industrial automation tasks. Any disruption in MQTT messaging could potentially leave users locked out of their homes and offices.
It's the smallest monthly update from the computing giant since 2020, but it does contain a patch for a concerning wormable vulnerability found in the Windows OS.
