xinetd daemon insecure permissions
|xinetd-insecure-permissions (6657)||Medium Risk|
The xinetd daemon in some Linux distributions creates files using insecure permissions. The default umask for xinetd is set to 0, resulting in all files created by applications using xinetd to be world writable. A local attacker could use this vulnerability to gain access to and modify unauthorized files.
