Package        : openldap
Version        : 2.4.44+dfsg-5+deb9u5
CVE ID         : none assigned yet

A vulnerability in the handling of normalization with modrdn was
discovered in OpenLDAP, a free implementation of the Lightweight
Directory Access Protocol. An unauthenticated remote attacker can
use this flaw to cause a denial of service (slapd daemon crash)
via a specially crafted packet.

For Debian 9 stretch, this problem has been fixed in version
2.4.44+dfsg-5+deb9u5.

We recommend that you upgrade your openldap packages.
