CVE-2018-17582
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.21%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
