[Jan Grashoefer (JIRA)]

Jan Grashoefer created BIT-1507:
-----------------------------------

             Summary: Intel framework does not match mail addresses properly
                 Key: BIT-1507
                 URL: https://bro-tracker.atlassian.net/browse/BIT-1507
             Project: Bro Issue Tracker
          Issue Type: Problem
          Components: Bro
    Affects Versions: 2.4
         Environment: All
            Reporter: Jan Grashoefer
            Priority: Low


Some time ago someone in #bro asked for matching mail addresses using the intel-framework. We realized, that the [seen-script|https://github.com/bro/bro/blob/master/scripts/policy/frameworks/intel/seen/smtp.bro] seems to contain a bug: Using {code}split_string_n(mail_address, /<.+>/, T, 1){code} to extract a mail address misses the last character and does not respect the possibility of multiple addresses.

I will add a pcap later.
