New Debian cyrus-sasl2 2.1.27~101-g0780600+dfsg-3+deb9u1 fixes:
This update addresses the following issue:
* cyrus-sasl (aka Cyrus SASL) 2.1.27 has an out-of-bounds write leading to  unauthenticated remote denial-of-service in OpenLDAP via a malformed LDAP  packet. The OpenLDAP crash is ultimately caused by an off-by-one error in  _sasl_add_string in common.c in cyrus-sasl. (CVE-2019-19906)
