The replication monitor CGI script (repl-monitor-cgi.pl) in Red Hat Administration Server, as used by Red Hat Directory Server 8.0 EL4 and EL5, allows remote attackers to execute arbitrary commands.
CVE-2008-2928 1 Redhat 1 Directory Server 2026-04-23 N/A
Multiple buffer overflows in the adminutil library in CGI applications in Red Hat Directory Server 7.1 before SP7 allow remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a crafted Accept-Language HTTP header.
CVE-2008-1677 1 Redhat 2 Directory Server, Fedora Directory Server 2026-04-23 N/A
Buffer overflow in the regular expression handler in Red Hat Directory Server 8.0 and 7.1 before SP6 allows remote attackers to cause a denial of service (slapd crash) and possibly execute arbitrary code via a crafted LDAP query that triggers the overflow during translation to a regular expression.
CVE-2006-0451 1 Redhat 2 Directory Server, Fedora Core 2026-04-16 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.

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-2006-0452 1 Redhat 2 Directory Server, Fedora Core 2026-04-16 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 2026-04-16 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-2024-8445 1 Redhat 3 Directory Server, Enterprise Linux, Rhel Els 2026-04-15 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-2025-4574 1 Redhat 7 Directory Server, Enterprise Linux, Openshift and 4 more 2026-04-15 6.5 Medium
In crossbeam-channel rust crate, the internal `Channel` type's `Drop` method has a race condition which could, in some circumstances, lead to a double-free that could result in memory corruption.
CVE-2024-3657 1 Redhat 5 Directory Server, Directory Server E4s, Directory Server Eus and 2 more 2026-04-15 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-2024-5953 1 Redhat 6 Directory Server, Directory Server E4s, Directory Server Eus and 3 more 2026-04-15 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-2025-2487 1 Redhat 4 Directory Server, Directory Server Eus, Enterprise Linux and 1 more 2026-04-15 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-2025-3416 1 Redhat 5 Directory Server, Enterprise Linux, Openshift and 2 more 2026-04-15 3.7 Low
A flaw was found in OpenSSL's handling of the properties argument in certain functions. This vulnerability can allow use-after-free exploitation, which may result in undefined behavior or incorrect property parsing, leading to OpenSSL treating the input as an empty string.
CVE-2024-2199 1 Redhat 4 Directory Server, Directory Server E4s, Enterprise Linux and 1 more 2026-04-15 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-2025-14905 1 Redhat 12 Directory Server, Directory Server E4s, Directory Server Eus and 9 more 2026-04-15 7.2 High
A flaw was found in the 389-ds-base server. A heap buffer overflow vulnerability exists in the `schema_attr_enum_callback` function within the `schema.c` file. This occurs because the code incorrectly calculates the buffer size by summing alias string lengths without accounting for additional formatting characters. When a large number of aliases are processed, this oversight can lead to a heap overflow, potentially allowing a remote attacker to cause a Denial of Service (DoS) or achieve Remote Code Execution (RCE).
CVE-2024-1062 2 Fedoraproject, Redhat 16 Fedora, 389 Directory Server, Directory Server and 13 more 2026-02-25 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-2024-6237 1 Redhat 3 389 Directory Server, Directory Server, Enterprise Linux 2025-11-20 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-2022-2850 4 Debian, Fedoraproject, Port389 and 1 more 6 Debian Linux, Fedora, 389-ds-base and 3 more 2025-11-04 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-2022-0918 2 Port389, Redhat 4 389-ds-base, Directory Server, Enterprise Linux and 1 more 2025-11-04 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-2021-4091 2 Port389, Redhat 11 389-ds-base, Directory Server, Enterprise Linux and 8 more 2025-11-04 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.
