CVE-2012-2668 1 Openldap 1 Openldap 2023-02-12 4.3 MEDIUM N/A
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.
CVE-2011-4079 1 Openldap 1 Openldap 2023-02-12 4.0 MEDIUM N/A
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.
CVE-2007-5707 1 Openldap 1 Openldap 2023-02-12 7.1 HIGH N/A
OpenLDAP before 2.3.39 allows remote attackers to cause a denial of service (slapd crash) via an LDAP request with a malformed objectClasses attribute. NOTE: this has been reported as a double free, but the reports are inconsistent.
CVE-2015-3276 2 Openldap, Redhat 5 Openldap, Enterprise Linux Desktop, Enterprise Linux Hpc Node and 2 more 2023-02-12 5.0 MEDIUM N/A
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.
CVE-2020-25692 3 Netapp, Openldap, Redhat 5 Cloud Backup, Solidfire Baseboard Management Controller, Solidfire Baseboard Management Controller Firmware and 2 more 2022-10-12 5.0 MEDIUM 7.5 HIGH
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.
CVE-2022-29155 3 Debian, Netapp, Openldap 14 Debian Linux, H300s, H300s Firmware and 11 more 2022-10-06 7.5 HIGH 9.8 CRITICAL
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.
CVE-2017-14159 2 Openldap, Oracle 2 Openldap, Blockchain Platform 2022-06-13 1.9 LOW 4.7 MEDIUM
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.
CVE-2017-9287 5 Debian, Mcafee, Openldap and 2 more 10 Debian Linux, Policy Auditor, Openldap and 7 more 2022-06-13 4.0 MEDIUM 6.5 MEDIUM
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.
CVE-2017-17740 4 Mcafee, Openldap, Opensuse and 1 more 4 Policy Auditor, Openldap, Leap and 1 more 2022-06-13 5.0 MEDIUM 7.5 HIGH
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.
CVE-2019-13565 7 Apple, Canonical, Debian and 4 more 9 Mac Os X, Ubuntu Linux, Debian Linux and 6 more 2022-06-13 5.0 MEDIUM 7.5 HIGH
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.
CVE-2019-13057 7 Apple, Canonical, Debian and 4 more 9 Mac Os X, Ubuntu Linux, Debian Linux and 6 more 2022-06-13 3.5 LOW 4.9 MEDIUM
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.)
CVE-2020-15719 5 Mcafee, Openldap, Opensuse and 2 more 5 Policy Auditor, Openldap, Leap and 2 more 2022-05-12 4.0 MEDIUM 4.2 MEDIUM
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.
CVE-2020-36230 4 Apache, Apple, Debian and 1 more 5 Bookkeeper, Mac Os X, Macos and 2 more 2022-04-29 5.0 MEDIUM 7.5 HIGH
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.
CVE-2020-12243 8 Apple, Broadcom, Canonical and 5 more 26 Mac Os X, Brocade Fabric Operating System, Ubuntu Linux and 23 more 2022-04-29 5.0 MEDIUM 7.5 HIGH
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).
CVE-2020-36229 3 Apple, Debian, Openldap 4 Mac Os X, Macos, Debian Linux and 1 more 2022-04-13 5.0 MEDIUM 7.5 HIGH
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.
CVE-2020-36228 3 Apple, Debian, Openldap 3 Macos, Debian Linux, Openldap 2022-04-13 5.0 MEDIUM 7.5 HIGH
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.
CVE-2020-36227 3 Apple, Debian, Openldap 3 Macos, Debian Linux, Openldap 2022-04-13 5.0 MEDIUM 7.5 HIGH
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.
CVE-2020-36226 3 Apple, Debian, Openldap 4 Mac Os X, Macos, Debian Linux and 1 more 2022-04-13 5.0 MEDIUM 7.5 HIGH
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.
CVE-2020-36225 3 Apple, Debian, Openldap 3 Macos, Debian Linux, Openldap 2022-04-13 5.0 MEDIUM 7.5 HIGH
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.
CVE-2020-36224 3 Apple, Debian, Openldap 4 Mac Os X, Macos, Debian Linux and 1 more 2022-04-13 5.0 MEDIUM 7.5 HIGH
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.
