Name of the Vulnerable Software and Affected Versions Tcpreplay version 4.3.2

Description The issue is related to a heap-buffer overflow in the randomize iparp function in edit packet.c, which allows attackers to cause a denial of service (DOS) via a crafted pcap file. This can be exploited by a remote attacker to disrupt service.
