Hi,

The following vulnerability was published for rust-coreutils.

CVE-2026-35368[0]:
| A vulnerability exists in the chroot utility of uutils coreutils
| when using the --userspec option. The utility resolves the user
| specification via getpwnam() after entering the chroot but before
| dropping root privileges. On glibc-based systems, this can trigger
| the Name Service Switch (NSS) to load shared libraries (e.g.,
| libnss_*.so.2) from the new root directory. If the NEWROOT is
| writable by an attacker, they can inject a malicious NSS module to
| execute arbitrary code as root, facilitating a full container escape
| or privilege escalation.
