CVE-2020-25692 3 Netapp, Openldap, Redhat 5 Cloud Backup, Solidfire Baseboard Management Controller, Solidfire Baseboard Management Controller Firmware and 2 more 2024-02-04 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.

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-2020-36223 3 Apple, Debian, Openldap 4 Mac Os X, Macos, Debian Linux and 1 more 2024-02-04 5.0 MEDIUM 7.5 HIGH
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).
CVE-2020-36228 3 Apple, Debian, Openldap 3 Macos, Debian Linux, Openldap 2024-02-04 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-2020-36221 3 Apple, Debian, Openldap 4 Mac Os X, Macos, Debian Linux and 1 more 2024-02-04 5.0 MEDIUM 7.5 HIGH
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).
CVE-2021-27212 2 Debian, Openldap 2 Debian Linux, Openldap 2024-02-04 5.0 MEDIUM 7.5 HIGH
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.
CVE-2020-36226 3 Apple, Debian, Openldap 4 Mac Os X, Macos, Debian Linux and 1 more 2024-02-04 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 2024-02-04 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-2020-36230 4 Apache, Apple, Debian and 1 more 5 Bookkeeper, Mac Os X, Macos and 2 more 2024-02-04 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-2020-36224 3 Apple, Debian, Openldap 4 Mac Os X, Macos, Debian Linux and 1 more 2024-02-04 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.
CVE-2020-36227 3 Apple, Debian, Openldap 3 Macos, Debian Linux, Openldap 2024-02-04 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-2020-15719 5 Mcafee, Openldap, Opensuse and 2 more 5 Policy Auditor, Openldap, Leap and 2 more 2024-02-04 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-2020-12243 8 Apple, Broadcom, Canonical and 5 more 26 Mac Os X, Brocade Fabric Operating System, Ubuntu Linux and 23 more 2024-02-04 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-2014-8182 2 Debian, Openldap 2 Debian Linux, Openldap 2024-02-04 4.3 MEDIUM 7.5 HIGH
An off-by-one error leading to a crash was discovered in openldap 2.4 when processing DNS SRV messages. If slapd was configured to use the dnssrv backend, an attacker could crash the service with crafted DNS responses.
CVE-2019-13057 7 Apple, Canonical, Debian and 4 more 9 Mac Os X, Ubuntu Linux, Debian Linux and 6 more 2024-02-04 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-2019-13565 7 Apple, Canonical, Debian and 4 more 9 Mac Os X, Ubuntu Linux, Debian Linux and 6 more 2024-02-04 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-2016-4984 2 Openldap, Redhat 2 Openldap-servers, Enterprise Linux 2024-02-04 1.9 LOW 4.7 MEDIUM
/usr/libexec/openldap/generate-server-cert.sh in openldap-servers sets weak permissions for the TLS certificate, which allows local users to obtain the TLS certificate by leveraging a race condition between the creation of the certificate, and the chmod to protect it.
CVE-2017-14159 2 Openldap, Oracle 2 Openldap, Blockchain Platform 2024-02-04 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-2017-17740 4 Mcafee, Openldap, Opensuse and 1 more 4 Policy Auditor, Openldap, Leap and 1 more 2024-02-04 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.
