Upgrade Ubuntu:16.04 tcpreplay to version 3.4.4-2+deb8u1ubuntu0.1~esm1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream tcpreplay package and not the tcpreplay package as distributed by Ubuntu.
See How to fix? for Ubuntu:16.04 relevant fixed versions and status.
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.
