What is CVE-2018-17582?
CVE-2018-17582 is a high-severity memory corruption vulnerability in Broadcom Tcpreplay, published on 28 Sep 2018. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
Tcpreplay v4.3.0 beta1 contains a heap-based buffer over-read.

This will result in a Denial of Service (DoS) and potentially Information Exposure when the application attempts to process a file.
