CVE-2025-2487 1 Redhat 4 Directory Server, Directory Server Eus, Enterprise Linux and 1 more 2025-04-08 4.9 Medium
A flaw was found in the 389-ds-base LDAP Server. This issue occurs when issuing a Modify DN LDAP operation through the ldap protocol, when the function return value is not tested and a NULL pointer is dereferenced. If a privileged user performs a ldap MODDN operation after a failed operation, it could lead to a Denial of Service (DoS) or system crash.
CVE-2004-1236 2 Netscape, Redhat 2 Directory Server, Directory Server 2025-04-03 N/A
Buffer overflow in the LDAP component for Netscape Directory Server (NDS) 3.6 on HP-UX and other operating systems allows remote attackers to execute arbitrary code.
CVE-2006-0451 1 Redhat 2 Directory Server, Fedora Core 2025-04-03 N/A
Multiple memory leaks in the LDAP component in Fedora Directory Server 1.0 allow remote attackers to cause a denial of service (memory consumption) via invalid BER packets that trigger an error, which might prevent memory from being freed if it was allocated during the ber_scanf call, as demonstrated using the ProtoVer LDAP test suite.
CVE-2006-0452 1 Redhat 2 Directory Server, Fedora Core 2025-04-03 N/A
dn2ancestor in the LDAP component in Fedora Directory Server 1.0 allows remote attackers to cause a denial of service (CPU and memory consumption) via a ModDN operation with a DN that contains a large number of "," (comma) characters, which results in a large amount of recursion, as demonstrated using the ProtoVer LDAP test suite.
CVE-2006-0453 1 Redhat 2 Directory Server, Fedora Core 2025-04-03 N/A
The LDAP component in Fedora Directory Server 1.0 allow remote attackers to cause a denial of service (crash) via a certain "bad BER sequence" that results in a free of uninitialized memory, as demonstrated using the ProtoVer LDAP test suite.
CVE-2023-1055 2 Fedoraproject, Redhat 2 Fedora, Directory Server 2025-03-11 5.5 Medium
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.
CVE-2024-5953 1 Redhat 6 Directory Server, Directory Server E4s, Directory Server Eus and 3 more 2025-02-18 5.7 Medium
A denial of service vulnerability was found in the 389-ds-base LDAP server. This issue may allow an authenticated user to cause a server denial of service while attempting to log in with a user with a malformed hash in their password.
CVE-2024-3657 1 Redhat 5 Directory Server, Directory Server E4s, Directory Server Eus and 2 more 2025-02-18 7.5 High
A flaw was found in 389-ds-base. A specially-crafted LDAP query can potentially cause a failure on the directory server, leading to a denial of service
CVE-2024-2199 1 Redhat 4 Directory Server, Directory Server E4s, Enterprise Linux and 1 more 2025-02-18 5.7 Medium
A denial of service vulnerability was found in 389-ds-base ldap server. This issue may allow an authenticated user to cause a server crash while modifying `userPassword` using malformed input.
CVE-2024-1062 2 Fedoraproject, Redhat 16 Fedora, 389 Directory Server, Directory Server and 13 more 2025-02-18 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-2022-0918 2 Port389, Redhat 4 389-ds-base, Directory Server, Enterprise Linux and 1 more 2025-02-13 7.5 High
A vulnerability was discovered in the 389 Directory Server that allows an unauthenticated attacker with network access to the LDAP port to cause a denial of service. The denial of service is triggered by a single message sent over a TCP connection, no bind or other authentication is required. The message triggers a segmentation fault that results in slapd crashing.
CVE-2022-2850 4 Debian, Fedoraproject, Port389 and 1 more 6 Debian Linux, Fedora, 389-ds-base and 3 more 2025-02-13 6.5 Medium
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.
CVE-2022-1949 2 Fedoraproject, Redhat 4 Fedora, 389 Directory Server, Directory Server and 1 more 2024-12-13 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-2024-8445 1 Redhat 3 Directory Server, Enterprise Linux, Rhel Els 2024-11-24 5.7 Medium
The fix for CVE-2024-2199 in 389-ds-base was insufficient to cover all scenarios. In certain product versions, an authenticated user may cause a server crash while modifying `userPassword` using malformed input.
CVE-2024-6237 1 Redhat 3 389 Directory Server, Directory Server, Enterprise Linux 2024-11-24 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-2021-4091 2 Port389, Redhat 11 389-ds-base, Directory Server, Enterprise Linux and 8 more 2024-11-21 7.5 High
A double-free was found in the way 389-ds-base handles virtual attributes context in persistent searches. An attacker could send a series of search requests, forcing the server to behave unexpectedly, and crash.
CVE-2021-3652 2 Port389, Redhat 4 389-ds-base, Directory Server, Enterprise Linux and 1 more 2024-11-21 6.5 Medium
A flaw was found in 389-ds-base. If an asterisk is imported as password hashes, either accidentally or maliciously, then instead of being inactive, any password will successfully match during authentication. This flaw allows an attacker to successfully authenticate as a user whose password was disabled.
CVE-2021-3514 1 Redhat 4 389 Directory Server, Directory Server, Enterprise Linux and 1 more 2024-11-21 6.5 Medium

CVE-2020-35518 1 Redhat 4 389 Directory Server, Directory Server, Enterprise Linux and 1 more 2024-11-21 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-2010-3282 3 Fedoraproject, Hp, Redhat 4 389 Directory Server, Hp-ux Directory Server, Directory Server and 1 more 2024-11-21 3.3 Low
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.
