OpenDMARC 1.4.1.1-1 core dumps with signal 6 (ABRT) when receiving e-mail from certain domains #186

Open AstroPig7 opened 3 years ago

AstroPig7 commented 3 years ago

Since upgrading to OpenDMARC 1.4.1.1-1, I’ve seen the program crash when receiving e-mail from domains like amazon.com, usps.com, and humblebundle.com. There doesn’t seem to be anything strange about their TXT records, so I assume something in the format of the e-mail is causing OpenDMARC to crash. From the system journal: Aug 26 07:32:05 mailx systemd[1]: opendmarc.service: Main process exited, code=dumped, status=6/ABRT

Unfortunately these stack traces are not terribly useful without line numbers. Make sure debug symbols are available. Also be sure that you have applied the patch set in #178.
