Adjacent-network process crash via unsigned payload underflow
Published Mar 20, 2024 · Updated Aug 2, 2024
Heap-based buffer overflow in eProsima Fast DDS allows remote attackers to terminate a subscriber with a crafted RTPS DATA Submessage. MessageReceiver::proc_Submsg_Data subtracts inline-QoS overhead from the submessage length into an unsigned payload_size without first rejecting a smaller length, wrapping the value before a copy. Exploitation requires sniffing the publisher GUID and reaching its subscriber over RTPS; success crashes the receiving Fast DDS process.
