Comment 1 Tomas Hoger 2017-04-24 09:44:10 UTC
The information shared by Oracle does not make it clear if this CVE is for an issue in the NULL Audit plugin that is part of the MySQL Community edition, or whether it applies to the MySQL Enterprise Audit feature of the MySQL Enterprise version.  It seems this may be for this issue corrected in the null_audit:

  For the null_audit plugin, setting the null_audit_event_record system
  variable improperly could cause a server exit. This variable should be
  set only from within the null_audit plugin, so it is now read only.
