Description Laura Pardo 2018-10-01 21:32:38 UTC
A flaw was found in tcpreplay v4.3.0. A heap-based buffer over-read in the get_next_packet() function in the send_packets.c file due to the use of 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.
