CVE-2010-0211The slap_modrdn2mods function in modrdn.c in OpenLDAP 2.4.22 does not check the return value of a call to the smr_normalize function, which allows remote attackers to cause a denial of service (segmentation fault) and possibly execute arbitrary code via a modrdn call with an RDN string containing invalid UTF-8 sequences, which triggers a free of an invalid, uninitialized pointer in the slap_mods_free function, as demonstrated using the Codenomicon LDAPv3 test suite.
CVE-2022-31253A Untrusted Search Path vulnerability in openldap2 of openSUSE Factory allows local attackers with control of the ldap user or group to change ownership of arbitrary directory entries to this user/group, leading to escalation to root. This issue affects: openSUSE Factory openldap2 versions prior to 2.6.3-404.1.
CVE-2021-27212In OpenLDAP through 2.4.57 and 2.5.x through 2.5.1alpha, an assertion failure in slapd can occur in the issuerAndThisUpdateCheck function via a crafted packet, resulting in a denial of service (daemon exit) via a short timestamp. This is related to schema_init.c and checkTime.
CVE-2020-36230A flaw was discovered in OpenLDAP before 2.4.57 leading in an assertion failure in slapd in the X.509 DN parsing in decode.c ber_next_element, resulting in denial of service.
CVE-2020-36229A flaw was discovered in ldap_X509dn2bv in OpenLDAP before 2.4.57 leading to a slapd crash in the X.509 DN parsing in ad_keystring, resulting in denial of service.
CVE-2020-36228An integer underflow was discovered in OpenLDAP before 2.4.57 leading to a slapd crash in the Certificate List Exact Assertion processing, resulting in denial of service.
CVE-2020-36227A flaw was discovered in OpenLDAP before 2.4.57 leading to an infinite loop in slapd with the cancel_extop Cancel operation, resulting in denial of service.
CVE-2020-36226A flaw was discovered in OpenLDAP before 2.4.57 leading to a memch->bv_len miscalculation and slapd crash in the saslAuthzTo processing, resulting in denial of service.
CVE-2020-36225A flaw was discovered in OpenLDAP before 2.4.57 leading to a double free and slapd crash in the saslAuthzTo processing, resulting in denial of service.
CVE-2020-36224A flaw was discovered in OpenLDAP before 2.4.57 leading to an invalid pointer free and slapd crash in the saslAuthzTo processing, resulting in denial of service.
CVE-2020-36223A flaw was discovered in OpenLDAP before 2.4.57 leading to a slapd crash in the Values Return Filter control handling, resulting in denial of service (double free and out-of-bounds read).
CVE-2020-36222A flaw was discovered in OpenLDAP before 2.4.57 leading to an assertion failure in slapd in the saslAuthzTo validation, resulting in denial of service.
CVE-2020-36221An integer underflow was discovered in OpenLDAP before 2.4.57 leading to slapd crashes in the Certificate Exact Assertion processing, resulting in denial of service (schema_init.c serialNumberAndIssuerCheck).
CVE-2020-25710A 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.
CVE-2020-25709A 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.
CVE-2020-25692A 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.
CVE-2020-12243In 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).
CVE-2015-3276The 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.
CVE-2019-13565An 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.
CVE-2023-2953A vulnerability was found in openldap. This security flaw causes a null pointer dereference in ber_memalloc_x() function.
CVE-2011-1025bind.cpp in back-ndb in OpenLDAP 2.4.x before 2.4.24 does not require authentication for the root Distinguished Name (DN), which allows remote attackers to bypass intended access restrictions via an arbitrary password.
CVE-2022-29155In OpenLDAP 2.x before 2.5.12 and 2.6.x before 2.6.2, a SQL injection vulnerability exists in the experimental back-sql backend to slapd, via a SQL statement within an LDAP query. This can occur during an LDAP search operation when the search filter is processed, due to a lack of proper escaping.
CVE-2019-13057An 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.)
CVE-2017-9287servers/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.
CVE-2017-17740contrib/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.
