"CVE-2018-10871

By default nsslapd-unhashed-pw-switch was set to 'on'. So a copy of
the unhashed password was kept in modifiers and was possibly logged in
changelog and retroCL.

Unless it is used by some plugin it does not require to keep
unhashed passwords. The nsslapd-unhashed-pw-switch option is
now 'off' by default.

CVE-2018-10935

It was discovered that any authenticated user doing a search using
ldapsearch with extended controls for server side sorting could bring
down the LDAP server itself.

The fix is to check if we are able to index the provided
value. If we are not, then slapd_qsort returns an error
(LDAP_OPERATION_ERROR) .

For Debian 8 'Jessie', these problems have been fixed in version
1.3.3.5-4+deb8u2.

We recommend that you upgrade your 389-ds-base packages.
