CVE-2026-11785 1 Redhat 3 389 Directory Server, Directory Server, Enterprise Linux 2026-06-12 N/A 4.3 MEDIUM
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.
CVE-2026-11786 1 Redhat 3 389 Directory Server, Directory Server, Enterprise Linux 2026-06-12 N/A 1.9 LOW
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.
CVE-2026-11787 1 Redhat 3 389 Directory Server, Directory Server, Enterprise Linux 2026-06-12 N/A 5.0 MEDIUM
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.
CVE-2026-11788 1 Redhat 3 389 Directory Server, Directory Server, Enterprise Linux 2026-06-12 N/A 5.9 MEDIUM
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.
CVE-2026-11789 1 Redhat 3 389 Directory Server, Directory Server, Enterprise Linux 2026-06-12 N/A 4.9 MEDIUM
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.
CVE-2026-11790 1 Redhat 3 389 Directory Server, Directory Server, Enterprise Linux 2026-06-12 N/A 4.9 MEDIUM
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.
CVE-2026-9064 1 Redhat 3 389 Directory Server, Directory Server, Enterprise Linux 2026-06-02 N/A 7.5 HIGH
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, worker thread starvation, or out-of-memory termination, resulting in a denial of service.
CVE-2022-0996 2 Fedoraproject, Redhat 3 Fedora, 389 Directory Server, Enterprise Linux 2025-11-03 4.0 MEDIUM 6.5 MEDIUM
A vulnerability was found in the 389 Directory Server that allows expired passwords to access the database to cause improper authentication.
CVE-2024-1062 2 Fedoraproject, Redhat 13 Fedora, 389 Directory Server, Directory Server and 10 more 2025-02-18 N/A 5.5 MEDIUM
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.
CVE-2022-1949 2 Fedoraproject, Redhat 4 Fedora, 389 Directory Server, Directory Server and 1 more 2024-12-13 5.0 MEDIUM 7.5 HIGH
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.
CVE-2024-6237 1 Redhat 3 389 Directory Server, Directory Server, Enterprise Linux 2024-11-21 N/A 6.5 MEDIUM
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.
CVE-2021-3514 1 Redhat 1 389 Directory Server 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
When using a sync_repl client in 389-ds-base, an authenticated attacker can cause a NULL pointer dereference using a specially crafted query, causing a crash.
CVE-2020-35518 1 Redhat 3 389 Directory Server, Directory Server, Enterprise Linux 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
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.
CVE-2018-10935 1 Redhat 1 389 Directory Server 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
A flaw was found in the 389 Directory Server that allows users to cause a crash in the LDAP server using ldapsearch with server side sort.
CVE-2010-2222 1 Redhat 2 389 Directory Server, Directory Server 2024-11-21 5.0 MEDIUM 7.5 HIGH
The _ger_parse_control function in Red Hat Directory Server 8 and the 389 Directory Server allows attackers to cause a denial of service (NULL pointer dereference) via a crafted search query.
