CVE-2026-35367
uutils coreutils nohup Information Disclosure via Insecure Default Output Permissions
Description
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.
