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.
