It was discovered that the SQL plugin in cyrus-sasl2, a library
implementing the Simple Authentication and Security Layer, is prone to a
SQL injection attack. An authenticated remote attacker can take advantage
of this flaw to execute arbitrary SQL commands and for privilege
escalation.
For Debian 9 stretch, this problem has been fixed in version
