HIGH Summary
A stack buffer overflow flaw was found in the way 389-ds-base 1.3.6.x before 1.3.6.13, 1.3.7.x before 1.3.7.9, 1.4.x before 1.4.0.5 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.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2018-0163.NASL description An update for 389-ds-base is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 389 Directory Server is an LDAP version 3 (LDAPv3) compliant server. The base packages include the Lightweight Directory Access Protocol (LDAP) server and command-line utilities for server administration. Security Fix(es) : * A stack-based buffer overflow 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-2017-15134) Bug Fix(es) : * Previously, when a connection received a high operation rate, Directory Server stopped to poll the connection in certain situations. As a consequence, new requests on the connection were not detected and processed. With this update, Directory Server correctly decides whether a connection has to be polled. As a result, connections with a high request rate no longer remain unprocessed. (BZ#1523505) * Previously, if Directory Server was stopped during an operation which created additional changes in the memory changelog, the Replication Update Vector (RUV) in the changelog was higher than the RUV in the database. As a consequence, Directory Server recreated the changelog when the server started. With this update, the server now writes the highest RUV to the changelog only if there is the highest Change Sequence Number (CSN) present in it. As a result, the database and the changelog RUV are consistent and the server does not need recreating the changelog at start up. (BZ#1523507) * Due to a bug, using a large number of Class of Service (CoS) templates in Directory Server increased the virtual attribute processing time. This update improves the structure of the CoS storage. As a result, using a large number of CoS templates no longer increases the virtual attribute processing time.

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.

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-2017-15134) Bug Fix(es) : - Previously, when a connection received a high operation rate, Directory Server stopped to poll the connection in certain situations. As a consequence, new requests on the connection were not detected and processed. With this update, Directory Server correctly decides whether a connection has to be polled. As a result, connections with a high request rate no longer remain unprocessed. - Previously, if Directory Server was stopped during an operation which created additional changes in the memory changelog, the Replication Update Vector (RUV) in the changelog was higher than the RUV in the database. As a consequence, Directory Server recreated the changelog when the server started. With this update, the server now writes the highest RUV to the changelog only if there is the highest Change Sequence Number (CSN) present in it. As a result, the database and the changelog RUV are consistent and the server does not need recreating the changelog at start up. - Due to a bug, using a large number of Class of Service (CoS) templates in Directory Server increased the virtual attribute processing time. This update improves the structure of the CoS storage. As a result, using a large number of CoS templates no longer increases the virtual attribute processing time. last seen 2020-03-18 modified 2018-01-25 plugin id 106338 published 2018-01-25 reporter This script is Copyright (C) 2018-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/106338 title Scientific Linux Security Update : 389-ds-base on SL7.x x86_64 (20180125) NASL family SuSE Local Security Checks NASL id SUSE_SU-2019-1207-1.NASL description 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).
