Description Laura Pardo 2018-10-01 21:28:37 UTC

A flaw was found in tcpreplay v4.3. A heap-based buffer over-read exists in the function fast_edit_packet() in the file send_packets.c. This can lead to Denial of Service (DoS) and potentially Information Exposure when the application attempts to process a crafted pcap file.
