15 CVE-2020-15719 295 2020-07-14 2021-07-31
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.
16 CVE-2020-12243 400 DoS 2020-04-28 2021-07-21

17 CVE-2019-13565 2019-07-26 2021-06-29
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.
18 CVE-2019-13057 2019-07-26 2021-07-31
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.)
19 CVE-2017-17740 119 DoS Overflow 2017-12-18 2021-07-31
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.
20 CVE-2017-14159 665 Exec Code 2017-09-05 2019-10-03
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.
21 CVE-2017-9287 415 2017-05-29 2021-07-31
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.
22 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.
23 CVE-2015-3276 310 2015-12-07 2016-10-15
5.0
None Remote Low Not required None Partial None
The nss_parse_ciphers function in libraries/libldap/tls_m.c in OpenLDAP does not properly parse OpenSSL-style multi-keyword mode cipher strings, which might cause a weaker than intended cipher to be used and allow remote attackers to have unspecified impact via unknown vectors.
24 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.
25 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.
26 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.
