A vulnerability was discovered in OpenLDAP, a free implementation of the Lightweight Directory Access Protocol. LDAP search filters with nested boolean expressions can result in denial of service (slapd daemon crash).

For Debian 8 Jessie, this problem has been fixed in version 2.4.40+dfsg-1+deb8u6.

We recommend that you upgrade your openldap packages.
