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.
