More information:

Several vulnerabilities were discovered in OpenLDAP, a free implementation of the Lightweight Directory Access Protocol. An unauthenticated remote attacker can take advantage of these flaws to cause a denial of service (slapd daemon crash, infinite loops) via specially crafted packets.

For Debian 9 stretch, these problems have been fixed in version 2.4.44+dfsg-5+deb9u7.

We recommend that you upgrade your openldap packages.
