Suggestion from Qalys:
If I may add one more thing, there is an issue that should be addressed
sooner rather than later: the writable configuration at the beginning of
the heap. A short-term (and hopefully non-intrusive) solution may be to
mmap() the configuration instead, and then mprotect(PROT_READ) it. This
would mitigate the exploitation technique that almost all Exim exploits
have been using.

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."

SECURITY: Avoid modification of constant data in dkim handling
Based on Heiko Schlittermann's commits
f880c7f3 and
c118c7f4. This
fixes:
6/ In src/pdkim/pdkim.c, pdkim_update_ctx_bodyhash() is sometimes called
with a global orig_data and hence canon_data, and the following line can
therefore modify data that should be constant:
773 canon_data->len = b->bodylength - b->signed_body_bytes;
For example, the following proof of concept sets lineending.len to 0
(this should not be possible):
(sleep 10; echo 'EHLO test'; sleep 3; echo 'MAIL FROM:<>'; sleep 3; echo 'RCPT TO:postmaster'; sleep 3; echo 'DATA'; date >&2; sleep 30; printf 'DKIM-Signature:a=rsa-sha1;c=simple/simple;l=0\r\n\r\n\r\nXXX\r\n.\r\n'; sleep 30) | nc -n -v 192.168.56.102 25
(gdb) print lineending
$1 = {data = 0x55e18035b2ad "\r\n", len = 2}
(gdb) print &lineending.len
$3 = (size_t *) 0x55e180385948 <lineending+8>
(gdb) watch *(size_t *) 0x55e180385948
Hardware watchpoint 1: *(size_t *) 0x55e180385948
Old value = 2
New value = 0
(gdb) print lineending
$5 = {data = 0x55e18035b2ad "\r\n", len = 0}

SECURITY: Leave a clean smtp_out input buffer even in case of read error
Based on Heiko Schlittermann's commit
54895bc3. This fixes:
7/ In src/smtp_out.c, read_response_line(), inblock->ptr is not updated
when -1 is returned. This does not seem to have bad consequences, but is
maybe not the intended behavior.
