* journald: check whether sscanf has changed the value corresponding to %nEvgeny Vereshchagin2018-11-171-0/+1
| | | | | | | | | It's possible for sscanf to receive strings containing all three fields and not matching the template at the same time. When this happens the value of k doesn't change, which basically means that process_audit_string tries to access memory randomly. Sometimes it works and sometimes it doesn't :-) See also https://bugzilla.redhat.com/show_bug.cgi?id=1059314.
* tests: add a fuzzer for process_audit_stringEvgeny Vereshchagin2018-11-161-0/+1
