Qualys discovered that needrestart, before version 3.8, allows local attackers to execute arbitrary code as root by winning a race condition and tricking needrestart into running their own, fake Python interpreter (instead of the systems real Python interpreter). The initial security fix (6ce6136) introduced a regression which was subsequently resolved (42af5d3).
