A vulnerability has been found in tcpreplay 4.3.0 and classified as critical. Affected by this vulnerability is the function get_next_packet
of the file send_packets.c. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer.
