Subject: [PATCH] SUDO: Create the socket with stricter permissions
|
|
|
|
This patch switches the sudo responder from being created as a public
|
|
responder where the permissions are open and not checked by the sssd
|
|
deaamon to a private socket. In this case, sssd creates the pipes with
|
|
strict permissions (see the umask in the call to create_pipe_fd() in
|
|
set_unix_socket()) and additionaly checks the permissions with every read
|
|
via the tevent integrations (see accept_fd_handler()).
