Security Fix(es) :

  - 389-ds-base: remote Denial of Service (DoS) via search     filters in SetUnicodeStringFromUTF_8 in collate.c     (CVE-2018-1054)

  - 389-ds-base: Authentication bypass due to lack of size     check in slapi_ct_memcmp function in ch_malloc.c     (CVE-2017-15135)

Security Fix(es) :

  - 389-ds-base: remote Denial of Service (DoS) via search     filters in SetUnicodeStringFromUTF_8 in collate.c     (CVE-2018-1054)

  - 389-ds-base: Authentication bypass due to lack of size     check in slapi_ct_memcmp function in ch_malloc.c     (CVE-2017-15135)

Bug Fix(es) :

  - Previously, if an administrator configured an index for     an attribute with a specific matching rule in the     'nsMatchingRule' parameter, Directory Server did not use     the retrieved indexer. As a consequence, Directory     Server did not index the values of this attribute with     the specified matching rules, and searches with extended     filters were unindexed. With this update, Directory     Server uses the retrieved indexer that processes the     specified matching rule. As a result, searches using     extended filters with a specified matching rule are now     indexed.

This update for 389-ds fixes the following issues :

The following security vulnerabilities were addressed :

CVE-2018-10850: Fixed a race condition on reference counter that would lead to a denial of service using persistent search (bsc#1096368)

CVE-2017-15134: Fixed a remote denial of service via search filters in slapi_filter_sprintf in slapd/util.c (bsc#1076530)

CVE-2017-15135: Fixed authentication bypass due to lack of size check in slapi_ct_memcmp function in ch_malloc.c (bsc#1076530)

CVE-2018-10935: Fixed an issue that allowed users to cause a crash via ldapsearch with server side sorts (bsc#1105606)

CVE-2018-14624: The lock controlling the error log was not correctly used when re-opening the log file in log__error_emergency(), allowing an attacker to send a flood of modifications to a very large DN, which could have caused slapd to crash (bsc#1106699).

According to the versions of the 389-ds-base packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - It was found that 389-ds-base since 1.3.6.1 up to and     including 1.4.0.3 did not always handle internal hash     comparison operations correctly during the     authentication process. A remote, unauthenticated     attacker could potentially use this flaw to bypass the     authentication process under very rare and specific     circumstances.(CVE-2017-15135)

  - An out-of-bounds memory read flaw was found in the way     389-ds-base handled certain LDAP search filters. A     remote, unauthenticated attacker could potentially use     this flaw to make ns-slapd crash via a specially     crafted LDAP request, thus resulting in denial of     service.(CVE-2018-1054)
