Debian DLA-1428-1 : 389-ds-base security update
High Nessus Plugin ID 111086
SynopsisThe remote Debian host is missing a security update.
DescriptionCVE-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 184.108.40.206-4+deb8u1.
We recommend that you upgrade your 389-ds-base packages.
