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:10 relevant fixed versions and status.

A heap-based buffer over-read was discovered in the tcpreplay-edit binary of Tcpreplay 4.3.0 beta1, during the incremental checksum operation. The issue gets triggered in the function csum_replace4() in incremental_checksum.h, causing a denial of service.
