|---|---|---|---|---|---|---|
| CVE-2026-15041 | A flaw was found in 389 Directory Server. The PBKDF2-SHA256 password verification function uses standard memcmp() for comparing password hashes instead of a constant-time comparison function. A remote attacker could potentially use timing measurements of LDAP bind attempts to infer partial hash information, though practical exploitation is extremely difficult due to PBKDF2 computational overhead. | [email protected] | 3.7 | 0.30% | 2026-07-08 | 2026-07-09 |
| CVE-2026-14969 | A flaw was found in 389-ds-base where the LDBM backend attribute encryption uses a hardcoded static initialization vector for AES-CBC and 3DES-CBC operations, allowing an attacker with privileged filesystem access to detect plaintext equality across encrypted entries by comparing ciphertext blocks. | [email protected] | 4.4 | 0.08% | 2026-07-07 | 2026-07-09 |
| CVE-2026-14940 | A heap-buffer-overflow flaw was found in 389 Directory Server (389-ds-base). When normalizing a Distinguished Name (DN) that contains a legacy-quoted value encoding a multivalued nested Relative Distinguished Name (RDN), the server can write past the end of a heap allocation while sorting RDN attribute-value pairs. An unauthenticated remote attacker can trigger this condition by sending an LDAP operation whose DN reaches the DN normalization routine, such as a search with a crafted base DN.

| CVE-2026-11791 | A flaw was found in 389 Directory Server. During schema reload, the attr_syntax_swap_ht() function unconditionally frees attribute syntax information nodes, bypassing the refcount-based deferred deletion used elsewhere in the attribute syntax subsystem. If an administrator triggers schema reload while concurrent LDAP query traffic is active, worker threads may access freed memory, resulting in use-after-free or double-free and a denial of service (server crash). | [email protected] | 5.0 | 0.21% | 2026-06-18 | 2026-06-30 |
| CVE-2026-12528 | A flaw was found in 389 Directory Server in the __aclp__normalize_acltxt() function of aclparse.c. A malformed ACI (Access Control Instruction) string can trigger heap-buffer-overflow writes and reads during ACI parsing. The function fails to validate that the ACI keyword has sufficient length after whitespace stripping, leading to a 1-byte out-of-bounds write and subsequent out-of-bounds reads. An authenticated user with write access to the aci attribute could send a crafted ACI value to silent | [email protected] | 5.4 | 0.23% | 2026-06-17 | 2026-06-27 |
| CVE-2026-11790 | A flaw was found in 389 Directory Server. The PBKDF2-SHA256 password storage plugin does not enforce an upper bound on the iteration count extracted from stored password hashes. A privileged attacker who can modify a user's password hash can cause excessive CPU consumption during authentication, resulting in denial of service. | [email protected] | 4.9 | 0.34% | 2026-06-09 | 2026-06-30 |
| CVE-2026-11789 | A flaw was found in 389 Directory Server. The SMD5 password storage plugin performs unsigned integer underflow when computing salt length from a crafted password hash shorter than 16 bytes, causing a buffer over-read that crashes the LDAP server during authentication. | [email protected] | 4.9 | 0.34% | 2026-06-09 | 2026-06-30 |
| CVE-2026-11788 | A flaw was found in 389 Directory Server. The dereference control plugin does not check for allocation failure before using a BER structure, allowing an unauthenticated remote attacker to crash the LDAP server when the system is under memory pressure. | [email protected] | 5.9 | 0.35% | 2026-06-09 | 2026-06-30 |
| CVE-2026-11787 | A flaw was found in 389 Directory Server. The ldap_utf8prev() function reads bytes before the start of a buffer without bounds checking, causing a heap buffer over-read in string filter parsing that may influence internal filter processing behavior. | [email protected] | 5.0 | 0.20% | 2026-06-09 | 2026-06-30 |
| CVE-2026-11786 | A flaw was found in 389 Directory Server. The LDIF parser reads past the end of a heap buffer when processing attribute types with trailing semicolons during database import, causing an out-of-bounds read detectable under memory instrumentation. | [email protected] | 1.9 | 0.17% | 2026-06-09 | 2026-06-30 |
| CVE-2026-11785 | A flaw was found in 389 Directory Server. A type confusion in the SSO token extended operation handler causes partial stack address information to be disclosed in LDAP responses to authenticated users. | [email protected] | 4.3 | 0.21% | 2026-06-09 | 2026-06-30 |
| CVE-2026-11611 | A flaw was found in 389 Directory Server. The Content Synchronization persistent search plugin allows unbounded memory growth when an authenticated client stops reading sync responses, enabling denial of service. Additional race conditions in plugin thread lifecycle can cause crashes during connection teardown or shutdown. | [email protected] | 6.5 | 0.24% | 2026-06-08 | 2026-06-30 |
| CVE-2026-9064 | A flaw was found in 389-ds-base. The get_ldapmessage_controls_ext() function in the LDAP server does not enforce an upper bound on the number of controls per LDAP message. A remote, unauthenticated attacker can send a specially crafted LDAP request containing hundreds of thousands of minimal controls within the default maximum BER message size (2 MB), causing excessive CPU consumption and heap allocation on the server. Under concurrent exploitation, this leads to significant latency degradation, | [email protected] | 7.5 | 0.79% | 2026-05-20 | 2026-06-29 |
| CVE-2024-6237 | A flaw was found in the 389 Directory Server. This flaw allows an unauthenticated user to cause a systematic server crash while sending a specific extended search request, leading to a denial of service. | [email protected] | 6.5 | 0.92% | 2024-07-09 | 2026-06-17 |
| CVE-2024-1062 | A heap overflow flaw was found in 389-ds-base. This issue leads to a denial of service when writing a value larger than 256 chars in log_entry_attr. | [email protected] | 5.5 | 0.30% | 2024-02-12 | 2026-06-17 |
| CVE-2023-1055 | A flaw was found in RHDS 11 and RHDS 12. While browsing entries LDAP tries to decode the userPassword attribute instead of the userCertificate attribute which could lead into sensitive information leaked. An attacker with a local account where the cockpit-389-ds is running can list the processes and display the hashed passwords. The highest threat from this vulnerability is to data confidentiality. | [email protected] | 5.5 | 0.19% | 2023-02-27 | 2026-06-17 |
| CVE-2022-2850 | A flaw was found In 389-ds-base. When the Content Synchronization plugin is enabled, an authenticated user can reach a NULL pointer dereference using a specially crafted query. This flaw allows an authenticated attacker to cause a denial of service. This CVE is assigned against an incomplete fix of CVE-2021-3514. | [email protected] | 6.5 | 1.24% | 2022-10-14 | 2026-06-17 |
| CVE-2022-1949 | An access control bypass vulnerability found in 389-ds-base. That mishandling of the filter that would yield incorrect results, but as that has progressed, can be determined that it actually is an access control bypass. This may allow any remote unauthenticated user to issue a filter that allows searching for database items they do not have access to, including but not limited to potentially userPassword hashes and other sensitive data. | [email protected] | 7.5 | 1.38% | 2022-06-02 | 2026-06-17 |
| CVE-2020-35518 | When binding against a DN during authentication, the reply from 389-ds-base will be different whether the DN exists or not. This can be used by an unauthenticated attacker to check the existence of an entry in the LDAP database. | [email protected] | 5.3 | 1.54% | 2021-03-26 | 2026-06-16 |
| CVE-2010-3282 | 389 Directory Server before 1.2.7.1 (aka Red Hat Directory Server 8.2) and HP-UX Directory Server before B.08.10.03, when audit logging is enabled, logs the Directory Manager password (nsslapd-rootpw) in cleartext when changing cn=config:nsslapd-rootpw, which might allow local users to obtain sensitive information by reading the log. | [email protected] | 3.3 | 0.26% | 2020-01-09 | 2026-06-16 |
