FINAL RESULTS:
data/tiny-initramfs-0.1/devices.c:124:19: [4] (race) access:
This usually indicates a security flaw. If an attacker can change anything
along the path between the call to access() and the file's actual use
(e.g., by moving files), the attacker can exploit the race condition
(CWE-362/CWE-367!). Set up the correct permissions (e.g., using setuid())
and try to open the file directly.
have_device = access(device, F_OK) != 0;

data/tiny-initramfs-0.1/tiny_initramfs.c:442:3: [4] (shell) execv:
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.

data/tiny-initramfs-0.1/tiny_initramfs.c:280:9: [3] (misc) chroot:
chroot can be very helpful, but is hard to use correctly (CWE-250, CWE-22).
Make sure the program immediately chdir("/"), closes file descriptors, and
drops root privileges, and that all necessary files (and no more!) are in
the new root.
