This looks potentially like a leaked file descriptor? Or is sendmail
reading and writing to a unix_stream_socket created by the bugzilla
cgi?
Could you run this in permissive mode to gather all of the avc messages.
I haven't reproduced the other AVC messages yet, but the above happens
when Bugzilla is sending mail after a bug changed.
This is what audit.log gives in permissive mode.
