13	CVE-2020-25710	617		2021-05-28	2021-09-14	5.0	None	Remote	Low	Not required	None	None	Partial
A flaw was found in OpenLDAP in versions before 2.4.56. This flaw allows an attacker who sends a malicious packet processed by OpenLDAP to force a failed assertion in csnNormalize23(). The highest threat from this vulnerability is to system availability.
14	CVE-2020-25709	617		2021-05-18	2021-09-14	5.0	None	Remote	Low	Not required	None	None	Partial
A flaw was found in OpenLDAP. This flaw allows an attacker who can send a malicious packet to be processed by OpenLDAP’s slapd server, to trigger an assertion failure. The highest threat from this vulnerability is to system availability.
15	CVE-2020-25692	476	DoS	2020-12-08	2022-10-12	5.0	None	Remote	Low	Not required	None	None	Partial
A NULL pointer dereference was found in OpenLDAP server and was fixed in openldap 2.4.55, during a request for renaming RDNs. An unauthenticated attacker could remotely crash the slapd process by sending a specially crafted request, causing a Denial of Service.
16	CVE-2020-15719	295		2020-07-14	2022-05-12	4.0	None	Remote	High	Not required	Partial	Partial	None
libldap in certain third-party OpenLDAP packages has a certificate-validation flaw when the third-party package is asserting RFC6125 support. It considers CN even when there is a non-matching subjectAltName (SAN). This is fixed in, for example, openldap-2.4.46-10.el8 in Red Hat Enterprise Linux.
17	CVE-2020-12243	674	DoS	2020-04-28	2022-04-29	5.0	None	Remote	Low	Not required	None	None	Partial
In filter.c in slapd in OpenLDAP before 2.4.50, LDAP search filters with nested boolean expressions can result in denial of service (daemon crash).
18	CVE-2019-13565			2019-07-26	2022-06-13	5.0	None	Remote	Low	Not required	Partial	None	None
An issue was discovered in OpenLDAP 2.x before 2.4.48. When using SASL authentication and session encryption, and relying on the SASL security layers in slapd access controls, it is possible to obtain access that would otherwise be denied via a simple bind for any identity covered in those ACLs. After the first SASL bind is completed, the sasl_ssf value is retained for all new non-SASL connections. Depending on the ACL configuration, this can affect different types of operations (searches, modifications, etc.). In other words, a successful authorization step completed by one user affects the authorization requirement for a different user.
19	CVE-2019-13057			2019-07-26	2022-06-13	3.5	None	Remote	Medium	???	Partial	None	None
An issue was discovered in the server in OpenLDAP before 2.4.48. When the server administrator delegates rootDN (database admin) privileges for certain databases but wants to maintain isolation (e.g., for multi-tenant deployments), slapd does not properly stop a rootDN from requesting authorization as an identity from another database during a SASL bind or with a proxyAuthz (RFC 4370) control. (It is not a common configuration to deploy a system where the server administrator and a DB administrator enjoy different levels of trust.)
20	CVE-2017-17740	119	DoS Overflow	2017-12-18	2022-06-13	5.0	None	Remote	Low	Not required	None	None	Partial
contrib/slapd-modules/nops/nops.c in OpenLDAP through 2.4.45, when both the nops module and the memberof overlay are enabled, attempts to free a buffer that was allocated on the stack, which allows remote attackers to cause a denial of service (slapd crash) via a member MODDN operation.
21	CVE-2017-14159	665	Exec Code	2017-09-05	2022-06-13	1.9	None	Local	Medium	Not required	None	None	Partial
slapd in OpenLDAP 2.4.45 and earlier creates a PID file after dropping privileges to a non-root account, which might allow local users to kill arbitrary processes by leveraging access to this non-root account for PID file modification before a root script executes a "kill `cat /pathname`" command, as demonstrated by openldap-initscript.
22	CVE-2017-9287	415		2017-05-29	2022-06-13	4.0	None	Remote	Low	???	None	None	Partial
servers/slapd/back-mdb/search.c in OpenLDAP through 2.4.44 is prone to a double free vulnerability. A user with access to search the directory can crash slapd by issuing a search including the Paged Results control with a page size of 0.
23	CVE-2015-6908	20	DoS	2015-09-11	2016-12-22	5.0	None	Remote	Low	Not required	None	None	Partial
The ber_get_next function in libraries/liblber/io.c in OpenLDAP 2.4.42 and earlier allows remote attackers to cause a denial of service (reachable assertion and application crash) via crafted BER data, as demonstrated by an attack against slapd.
24	CVE-2015-3276	310		2015-12-07	2023-02-02	5.0	None	Remote	Low	Not required	None	Partial	None
A flaw was found in the way OpenLDAP parsed OpenSSL-style cipher strings. As a result, OpenLDAP could potentially use ciphers that were not intended to be enabled.
25	CVE-2013-4449	189	DoS	2014-02-05	2016-12-08	4.3	None	Remote	Medium	Not required	None	None	Partial
The rwm overlay in OpenLDAP 2.4.23, 2.4.36, and earlier does not properly count references, which allows remote attackers to cause a denial of service (slapd crash) by unbinding immediately after a search request, which triggers rwm_conn_destroy to free the session context while it is being used by rwm_op_search.
26	CVE-2012-2668	200	+Info	2012-06-17	2017-08-29	4.3	None	Remote	Medium	Not required	Partial	None	None
libraries/libldap/tls_m.c in OpenLDAP, possibly 2.4.31 and earlier, when using the Mozilla NSS backend, always uses the default cipher suite even when TLSCipherSuite is set, which might cause OpenLDAP to use weaker ciphers than intended and make it easier for remote attackers to obtain sensitive information.
27	CVE-2012-1164	119	DoS Overflow	2012-06-29	2017-01-07	2.6	None	Remote	High	Not required	None	None	Partial
slapd in OpenLDAP before 2.4.30 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via an LDAP search query with attrsOnly set to true, which causes empty attributes to be returned.
28	CVE-2011-4079	189	DoS Overflow	2011-10-27	2017-08-29	4.0	None	Remote	Low	???	None	None	Partial
Off-by-one error in the UTF8StringNormalize function in OpenLDAP 2.4.26 and earlier allows remote attackers to cause a denial of service (slapd crash) via a zero-length string that triggers a heap-based buffer overflow, as demonstrated using an empty postalAddressAttribute value in an LDIF entry.
29	CVE-2007-6698	399	DoS	2008-02-01	2018-10-15	4.0	None	Remote	Low	???	None	None	Partial
The BDB backend for slapd in OpenLDAP before 2.3.36 allows remote authenticated users to cause a denial of service (crash) via a potentially-successful modify operation with the NOOP control set to critical, possibly due to a double free vulnerability.
30	CVE-2006-6493		Exec Code Overflow	2006-12-13	2011-03-08	5.1	None	Remote	High	Not required	Partial	Partial	Partial
Buffer overflow in the krbv4_ldap_auth function in servers/slapd/kerberos.c in OpenLDAP 2.4.3 and earlier, when OpenLDAP is compiled with the --enable-kbind (Kerberos KBIND) option, allows remote attackers to execute arbitrary code via an LDAP bind request using the LDAP_AUTH_KRBV41 authentication method and long credential data.
31	CVE-2006-5779	399	DoS	2006-11-07	2018-10-17	5.0	None	Remote	Low	Not required	None	None	Partial
OpenLDAP before 2.3.29 allows remote attackers to cause a denial of service (daemon crash) via LDAP BIND requests with long authcid names, which triggers an assertion failure.
32	CVE-2005-4442		+Priv	2005-12-21	2008-09-05	7.2	None	Local	Low	Not required	Complete	Complete	Complete
Untrusted search path vulnerability in OpenLDAP before 2.2.28-r3 on Gentoo Linux allows local users in the portage group to gain privileges via a malicious shared object in the Portage temporary build directory, which is part of the RUNPATH.
33	CVE-2002-1508			2003-02-19	2008-09-10	1.2	None	Local	High	Not required	None	Partial	None
slapd in OpenLDAP2 (OpenLDAP 2) 2.2.0 and earlier allows local users to overwrite arbitrary files via a race condition during the creation of a log file for rejected replication requests.
34	CVE-2002-1379		Exec Code	2003-01-02	2008-09-10	7.5	None	Remote	Low	Not required	Partial	Partial	Partial
OpenLDAP2 (OpenLDAP 2) 2.2.0 and earlier allows remote or local attackers to execute arbitrary code when libldap reads the .ldaprc file within applications that are running with extra privileges.
35	CVE-2002-1378		Exec Code Overflow	2003-01-02	2017-07-11	7.5	None	Remote	Low	Not required	Partial	Partial	Partial
Multiple buffer overflows in OpenLDAP2 (OpenLDAP 2) 2.2.0 and earlier allow remote attackers to execute arbitrary code via (1) long -t or -r parameters to slurpd, (2) a malicious ldapfilter.conf file that is not properly handled by getfilter functions, (3) a malicious ldaptemplates.conf that causes an overflow in libldap, (4) a certain access control list that causes an overflow in slapd, or (5) a long generated filename for logging rejected replication requests.
36	CVE-2002-0045			2002-01-31	2017-10-10	7.5	None	Remote	Low	Not required	Partial	Partial	Partial
slapd in OpenLDAP 2.0 through 2.0.19 allows local users, and anonymous users before 2.0.8, to conduct a "replace" action on access controls without any values, which causes OpenLDAP to delete non-mandatory attributes that would otherwise be protected by ACLs.
