FINAL RESULTS:

data/tilix-1.9.3/experimental/flatpak/tilix-flatpak-toolbox.c:14:9:  [4] (shell) execlp:
  This causes a new program to execute and is difficult to use safely
  (CWE-78). try using a library call that implements the same functionality
  if available.
        execlp("getent", "getent", "passwd", argv[2], NULL);
data/tilix-1.9.3/experimental/flatpak/tilix-flatpak-toolbox.c:28:9:  [2] (buffer) char:
  Statically-sized arrays can be improperly restricted, leading to potential
  overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
  functions that limit length, or ensure that the size is larger than the
  maximum possible length.
        char path[32];
data/tilix-1.9.3/experimental/flatpak/tilix-flatpak-toolbox.c:31:20:  [2] (misc) fopen:
  Check when opening files - can an attacker redirect it (via symlinks),
  force the opening of special file type (e.g., device files), move things
  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).
        FILE *fp = fopen(path, "r");
data/tilix-1.9.3/experimental/flatpak/tilix-flatpak-toolbox.c:38:13:  [2] (buffer) char:
  Statically-sized arrays can be improperly restricted, leading to potential
  overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
  functions that limit length, or ensure that the size is larger than the
  maximum possible length.
            char buf[1024];
