CVE-2015-1854
      A flaw was found while doing authorization of modrdn operations.

      Improper handling of a search filter in slapi_filter_sprintf()
      in slapd/util.c can lead to remote server crash and denial
      of service.

CVE-2018-1054
      When read access on  is enabled, a flaw in
      SetUnicodeStringFromUTF_8 function in collate.c, can lead to
      out-of-bounds memory operations.
      This might result in a server crash, caused by unauthorized
      users.

CVE-2018-1089
      Any user (anonymous or authenticated) can crash ns-slapd with a
      crafted ldapsearch query with very long filter value.

CVE-2018-10850
      Due to a race condition the server could crash in turbo mode

      trigger a denial of service.
