Hi,

The following vulnerability was published for rust-coreutils.

CVE-2026-35367[0]:
| The nohup utility in uutils coreutils creates its default output
| file, nohup.out, without specifying explicit restricted permissions.
| This causes the file to inherit umask-based permissions, typically
| resulting in a world-readable file (0644). In multi-user
| environments, this allows any user on the system to read the
| captured stdout/stderr output of a command, potentially exposing
| sensitive information. This behavior diverges from GNU coreutils,
| which creates nohup.out with owner-only (0600) permissions.
