Prior to versions 3.4.1, 3.3.1, and 2.6.11, a remotely triggerable Out-of-Memory (OOM) denial-of-service exists in Fast\n-DDS when processing RTPS GAP submessages under RELIABLE QoS. By sending a tiny GAP packet with a huge gap range (`gapList\n.base - gapStart`), an attacker drives `StatefulReader::processGapMsg()` into an unbounded loop that inserts millions of s\nequence numbers into `WriterProxy::changes_received_` (`std::set`), causing multi-GB heap growth and process termination. \nNo authentication is required beyond network reachability to the reader on the DDS domain. In environments without an RSS \nlimit (non-ASan / unlimited), memory consumption was observed to rise to ~64 GB. Versions 3.4.1, 3.3.1, and 2.6.11 patch t\nhe issue."},{"lang":"es","value":"Fast DDS es una implementación en C++ del estándar DDS (Data Distribution Service) de la OMG (Object Management Group). Antes de las versiones 3.4.1, 3.3.1 y 2.6.11, existe una denegación de servicio por falta de memoria (OOM) que puede ser activada remotamente en Fast-DDS al procesar submensajes RTPS GAP bajo QoS RELIABLE. Al enviar un pequeño paquete GAP con un enorme rango de brecha ('gapList.base - gapStart'), un atacante lleva a 'StatefulReader::processGapMsg()' a un bucle ilimitado que inserta millones de números de secuencia en 'WriterProxy::changes_received_' ('std::set'), causando un crecimiento de la pila de varios GB y la terminación del proceso. No se requiere autenticación más allá de la accesibilidad de red al lector en el dominio DDS. En entornos sin un límite de RSS (no-ASan / ilimitado), se observó que el consumo de memoria aumentaba a ~64 GB.
