Until a fix is available, ensure that the new root directory (NEWROOT) is not writable by untrusted users to prevent injection of malicious NSS modules.

Description

A vulnerability in the chroot utility of rust-coreutils affects the --userspec option. The utility resolves user specifications after entering the chroot but before dropping root privileges, which on glibc-based systems can cause the Name Service Switch (NSS) to load shared libraries from the new root directory. If the new root directory is writable by an attacker, they can inject a malicious NSS module, enabling arbitrary code execution as root and potentially leading to container escape or privilege escalation.
