Descriptions

Tcpreplay v4.3.0 beta1 contains a heap-based buffer over-read. The get_next_packet() function in the send_packets.c file uses the memcpy() function unsafely to copy sequences from the source buffer pktdata to the destination (*prev_packet)->pktdata. This will result in a Denial of Service (DoS) and potentially Information Exposure when the application attempts to process a file.

tcpreplay v4.3.0 contiene una sobrelectura de búfer basada en memoria dinámica (heap). La función get_next_packet() en el archivo send_packets.c emplea la función memcpy() de forma no segura para copiar secuencias del búfer de origen pktdata al destino (*prev_packet)->pktdata. Esto resultará en una denegación de servicio (DoS) y una potencial exposición de información cuando la aplicación intenta procesar un archivo.
