FKIE_CVE-2018-17582

Vulnerability from fkie_nvd - Published: 2018-09-28 09:29 - Updated: 2026-06-17 01:46

Severity

7.1 (High) - CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:H

Summary

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.
