CVE-2018-17974 (opens in a new tab)How to fix?
There is no fixed version for Debian:9 tcpreplay.
NVD Description
Note: Versions mentioned in the description apply only to the upstream tcpreplay package and not the tcpreplay package as distributed by Debian.
See How to fix? for Debian:9 relevant fixed versions and status.
An issue was discovered in Tcpreplay 4.3.0 beta1. A heap-based buffer over-read was triggered in the function dlt_en10mb_encode() of the file plugins/dlt_en10mb/en10mb.c, due to inappropriate values in the function memmove(). The length (pktlen + ctx -> l2len) can be larger than source value (packet + ctx->l2len) because the function fails to ensure the length of a packet is valid. This leads to Denial of Service.
