2021-05-27CVE-2020-28007: Link attack in Exim's log directoryQualys Security Advisory
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."

2021-05-27SECURITY: Avoid modification of constant data in dkim handlingHeiko Schlittermann (HS12-RIPE)
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} (cherry picked from commit 92359a62a0e31734ad8069c66f64b37f9eaaccbe) (cherry picked from commit c5f2f5cf2a6b45ae7ba0ed15e04fbe014727b210)
2021-05-27SECURITY: Leave a clean smtp_out input buffer even in case of read errorHeiko Schlittermann (HS12-RIPE)
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.
