| CVE | CVSS | EPSS | Vendor, product | Description | Modified |
|---|---|---|---|---|---|
| CVE-2020-36228 | 7.5 high | 85.0% | openldap, debian, debian_linux, macos | An 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. | 14 Oct |
| CVE-2020-36221 | 7.5 high | 85.0% | openldap, debian, debian_linux, mac_os_x | An 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). | 14 Oct |
| CVE-2020-36227 | 7.5 high | 77.0% | openldap, debian, debian_linux, macos | A 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. | 14 Oct |
| CVE-2020-36222 | 7.5 high | 77.0% | openldap, debian, debian_linux, mac_os_x | A 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. | 14 Oct |
| CVE-2021-27212 | 7.5 high | 66.0% | openldap, debian, debian_linux | In 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. | 14 Oct |
| CVE-2022-29155 | 9.8 critical | 64.0% | openldap, debian, debian_linux, h300s_firmware | In 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. | 14 Oct |
| CVE-2020-36230 | 7.5 high | 12.0% | openldap, debian, debian_linux, mac_os_x | A 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. | 14 Oct |
| CVE-2019-19906 | 7.5 high | 8.0% | cyrusimap, debian, cyrus-sasl, debian_linux, ubuntu_linux | cyrus-sasl (aka Cyrus SASL) 2.1.27 has an out-of-bounds write leading to unauthenticated remote denial-of-service in OpenLDAP via a malformed LDAP packet. The OpenLDAP crash is ultimately caused by an off-by-one error in _sasl_add_string in common.c in cyrus-sasl. | 14 Oct |
| CVE-2019-13057 | 4.9 medium | 7.0% | openldap, canonical, ubuntu_linux, debian_linux | 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.) | 14 Oct |
| CVE-2020-12243 | 7.5 high | 5.0% | openldap, debian, debian_linux, leap | 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). | 14 Oct |
| CVE-2019-13565 | 7.5 high | 5.0% | openldap, canonical, ubuntu_linux, debian_linux | 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. | 14 Oct |
| CVE-2020-36229 | 7.5 high | 4.0% | openldap, debian, debian_linux, mac_os_x | A 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. | 14 Oct |
| CVE-2020-36226 | 7.5 high | 4.0% | openldap, debian, debian_linux, mac_os_x | A 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. | 14 Oct |
| CVE-2020-36225 | 7.5 high | 4.0% | openldap, debian, debian_linux, macos | A 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. | 14 Oct |
| CVE-2020-36224 | 7.5 high | 4.0% | openldap, debian, debian_linux, mac_os_x | A 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. | 14 Oct |
| CVE-2020-36223 | 7.5 high | 4.0% | openldap, debian, debian_linux, mac_os_x | A 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). | 14 Oct |
| CVE-2022-22576 | 8.1 high | 3.0% | haxx, debian, curl, debian_linux, clustered_data_ontap | An improper authentication vulnerability exists in curl 7.33.0 to and including 7.82.0 which might allow reuse OAUTH2-authenticated connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. This affects SASL-enabled protocols: SMPTP(S), IMAP(S), POP3(S) and LDAP(S) (openldap only). | 14 Oct |
| CVE-2020-25710 | 7.5 high | 3.0% | openldap, redhat, jboss_core_services, jboss_enterprise_application_platform | 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 Oct |
| CVE-2020-25709 | 7.5 high | 3.0% | openldap, debian, debian_linux, mac_os_x | 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. | 14 Oct |
| CVE-2020-25692 | 7.5 high | 3.0% | openldap, redhat, enterprise_linux, cloud_backup | 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. | 14 Oct |
| CVE-2023-2953 | 7.5 high | 2.0% | openldap, redhat, enterprise_linux, macos | A vulnerability was found in openldap. This security flaw causes a null pointer dereference in ber_memalloc_x() function. | 14 Oct |
