Qualys Security Advisory [Tue, 23 Feb 2021 16:33:03 +0000 (08:33 -0800)]
CVE-2020-28007: Link attack in Exim's log directory

We patch this vulnerability by opening (instead of just creating) the
log file in an unprivileged (exim) child process, and by passing this
file descriptor back to the privileged (root) parent process. The two
functions log_send_fd() and log_recv_fd() are inspired by OpenSSH's
functions mm_send_fd() and mm_receive_fd(); thanks!

This patch also fixes:

- a NULL-pointer dereference in usr1_handler() (this signal handler is
  installed before process_log_path is initialized);

- a file-descriptor leak in dmarc_write_history_file() (two return paths
  did not close history_file_fd).

Note: the use of log_open_as_exim() in dmarc_write_history_file() should
be fine because the documentation explicitly states "Make sure the
directory of this file is writable by the user exim runs as."
