File 0001-SUDO-Create-the-socket-with-stricter-permissions.patch of Package sssd.30908
From 06193adc0de042484f672cadd0808c78c5ebb70e Mon Sep 17 00:00:00 2001 From: Jakub Hrozek <jhrozek@redhat.com> Date: Fri, 15 Jun 2018 22:29:34 +0200 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()). --- src/responder/sudo/sudosrv.c | 3 ++- src/sysv/systemd/sssd-sudo.socket.in | 1 + 2 files changed, 3 insertions(+), 1 deletion(-) diff --git a/src/responder/sudo/sudosrv.c b/src/responder/sudo/sudosrv.c index ac4258710d3a9b48285522abd23bdd59ba42ad4e..e87a24499c2d82fafaa8e1f9b386e44332394266 100644 --- a/src/responder/sudo/sudosrv.c +++ b/src/responder/sudo/sudosrv.c @@ -79,7 +79,8 @@ int sudo_process_init(TALLOC_CTX *mem_ctx, sudo_cmds = get_sudo_cmds(); ret = sss_process_init(mem_ctx, ev, cdb, sudo_cmds, - SSS_SUDO_SOCKET_NAME, -1, NULL, -1, + NULL, -1, /* No public socket */ + SSS_SUDO_SOCKET_NAME, -1, /* Private socket only */ CONFDB_SUDO_CONF_ENTRY, SSS_SUDO_SBUS_SERVICE_NAME, SSS_SUDO_SBUS_SERVICE_VERSION, diff --git a/src/sysv/systemd/sssd-sudo.socket.in b/src/sysv/systemd/sssd-sudo.socket.in index c9abb875f0accbaf58d78846020fef74c7473528..96a8b0327ddb4d331c9b2e97ece3453f8f76872d 100644 --- a/src/sysv/systemd/sssd-sudo.socket.in +++ b/src/sysv/systemd/sssd-sudo.socket.in @@ -11,6 +11,7 @@ ExecStartPre=@libexecdir@/sssd/sssd_check_socket_activated_responders -r sudo ListenStream=@pipepath@/sudo SocketUser=@SSSD_USER@ SocketGroup=@SSSD_USER@ +SocketMode=0600 [Install] WantedBy=sssd.service -- 2.14.3
