Package        : 389-ds-base
Version        : 1.3.3.5-4+deb8u1
CVE ID         : CVE-2015-1854 CVE-2017-15134 CVE-2018-1054 CVE-2018-1089
                  CVE-2018-10850


CVE-2015-1854
      A flaw was found while doing authorization of modrdn operations.
      An unauthenticated attacker able to issue an ldapmodrdn call to
      the directory server could perform unauthorized modifications
      of entries in the directory server.

CVE-2017-15134
      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 <attribute_name> 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
      (because of high traffic) or when a worker reads several requests
      in the read buffer (more_data). Thus an anonymous attacker could
      trigger a denial of service.


For Debian 8 "Jessie", these problems have been fixed in version
1.3.3.5-4+deb8u1.

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