CVE-2026-35367 Details
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.
A vulnerability exists in the uutils coreutils nohup utility, which creates the default output file nohup.out without setting explicit restricted permissions. This oversight allows the file to inherit umask-based permissions, typically resulting in world-readable files. In multi-user environments, this could enable any user to access the stdout or stderr output of a command, potentially revealing sensitive information. This behavior contrasts with GNU coreutils, which properly sets nohup.out permissions to owner-only.
A pull request has been made to address this vulnerability by changing the output file permissions to the correct owner-only setting. Users can apply this update by following the instructions in the pull request.
