NVD Description

Note: Versions mentioned in the description apply only to the upstream tcpreplay package and not the tcpreplay package as distributed by Ubuntu.

Heap-buffer overflow in the randomize_iparp function in edit_packet.c. of Tcpreplay v4.3.2 allows attackers to cause a denial of service (DOS) via a crafted pcap.
