(** This module implements a check for CWE-243: Creation of chroot Jail Without Changing Working Directory. Creating a chroot Jail without changing the working directory afterwards does not prevent access to files outside of the jail. See {: https://cwe.mitre.org/data/definitions/243.html} for detailed a description. {1 How the check works} According to {: http://www.unixwiz.net/techtips/chroot-practices.html}, there are several ways to achieve the safe creation of a chroot jail, e.g. chdir -> chroot -> setuid. They are configurable in config.json. We check whether each function that calls chroot is using one of these safe call sequences to do so. If not, a warning is emitted. {1 False Positives} None known. {1 False Negatives} None known. *) val name : string val version : string val check_cwe : Bap.Std.program Bap.Std.term -> Bap.Std.project -> Bap.Std.word Bap.Std.Tid.Map.t -> string list list -> string list -> unit
