| CVE-2016-5405 | Cri | 0.64 | 9.8 | 0.03 | Jun 8, 2017 | 389 Directory Server in Red Hat Enterprise Linux Desktop 6 through 7, Red Hat Enterprise Linux HPC Node 6 through 7, Red Hat Enterprise Linux Server 6 through 7, and Red Hat Enterprise Linux Workstation 6 through 7 allows remote attackers to obtain user passwords. | ||
| CVE-2026-15722 | Hig | 0.49 | 7.5 | 0.00 | Jul 31, 2026 | A stack buffer overflow flaw was found in 389 Directory Server (389-ds-base). The get_ruvelement_from_berval() function in repl5_ruv.c copies digit characters from a network-supplied RUV berval into a fixed 16-byte stack buffer without bounds checking. A remote unauthenticated… | ||
| CVE-2026-11770 | Hig | 0.49 | 7.5 | 0.00 | Jul 31, 2026 | A flaw was found in 389 Directory Server.

A remote, unauthenticated attacker can send a specially crafted LDAP request containing hundreds of… | ||
| CVE-2022-1949 | Hig | 0.49 | 7.5 | 0.01 | Jun 2, 2022 | 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… | ||
| CVE-2010-2222 | Hig | 0.49 | 7.5 | 0.01 | Nov 5, 2019 | 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. | ||

| CVE-2018-10935 | Med | 0.42 | 6.5 | 0.02 | Sep 11, 2018 | 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-2026-11788 | Med | 0.38 | 5.9 | 0.00 | Jun 9, 2026 | 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-2024-1062 | Med | 0.36 | 5.5 | 0.00 | Feb 12, 2024 | 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-2023-1055 | Med | 0.36 | 5.5 | 0.00 | Feb 27, 2023 | A flaw was found in RHDS 11 and RHDS 12.
