CVE-2018-1054 [HIGH] CVE-2018-1054: An out-of-bounds memory read flaw was found in the way 389-ds-base handled certain LDAP search filters, affecting all versions including 1 An out-of-bounds memory read flaw was found in the way 389-ds-base handled certain LDAP search filters, affecting all versions including 1.4.x. A remote, unauthenticated attacker could potentially use this flaw to make ns-slapd crash via a specially crafted LDAP request, thus resulting in denial of service.

CVE-2018-1089 [HIGH] CVE-2018-1089: 389-ds-base before versions 1 389-ds-base before versions 1.4.0.9, 1.3.8.1, 1.3.6.15 did not properly handle long search filters with characters needing escapes, possibly leading to buffer overflows. A remote, unauthenticated attacker could potentially use this flaw to make ns-slapd crash via a specially crafted LDAP request, thus resulting in denial of service.

CVE-2017-15134 [HIGH] CVE-2017-15134: A stack buffer overflow flaw was found in the way 389-ds-base 1 A stack buffer overflow flaw was found in the way 389-ds-base 1.3.6.x before 1.3.6.13, 1.3.7.x before 1.3.7.9, 1.4.x before 1.4.0.5 handled certain LDAP search filters. A remote, unauthenticated attacker could potentially use this flaw to make ns-slapd crash via a specially crafted LDAP request, thus resulting in denial of service.

CVE-2015-1854 [HIGH] CVE-2015-1854: 389 Directory Server before 1 389 Directory Server before 1.3.3.10 allows attackers to bypass intended access restrictions and modify directory entries via a crafted ldapmodrdn call.

CVE-2015-3230 [HIGH] CVE-2015-3230: 389 Directory Server (formerly Fedora Directory Server) before 1 389 Directory Server (formerly Fedora Directory Server) before 1.3.3.12 does not enforce the nsSSL3Ciphers preference when creating an sslSocket, which allows remote attackers to have unspecified impact by requesting to use a disabled cipher.

CVE-2017-2591 [HIGH] CVE-2017-2591: 389-ds-base before version 1 389-ds-base before version 1.3.6 is vulnerable to an improperly NULL terminated array in the uniqueness_entry_to_config() function in the "attribute uniqueness" plugin of 389 Directory Server. An authenticated, or possibly unauthenticated, attacker could use this flaw to force an out-of-bound heap memory read, possibly triggering a crash of the LDAP service.

CVE-2022-0996 [MEDIUM] CVE-2022-0996: A vulnerability was found in the 389 Directory Server that allows expired passwords to access the database to cause improper authentication A vulnerability was found in the 389 Directory Server that allows expired passwords to access the database to cause improper authentication.

CVE-2021-4091 [HIGH] CWE-415 CVE-2021-4091: A double-free was found in the way 389-ds-base handles virtual attributes context in persistent sear 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-2024-3657 [HIGH] CVE-2024-3657: A flaw was found in 389-ds-base 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-2018-10871 [HIGH] CVE-2018-10871: 389-ds-base before versions 1 389-ds-base before versions 1.3.8.5, 1.4.0.12 is vulnerable to a Cleartext Storage of Sensitive Information. By default, when the Replica and/or retroChangeLog plugins are enabled, 389-ds-base stores passwords in plaintext format in their respective changelog files. An attacker with sufficiently high privileges, such as root or Directory Manager, can query these files in order to retrieve plaintext passwords.

CVE-2014-0132 [MEDIUM] CVE-2014-0132: The SASL authentication functionality in 389 Directory Server before 1 The SASL authentication functionality in 389 Directory Server before 1.2.11.26 allows remote authenticated users to connect as an arbitrary user and gain privileges via the authzid parameter in a SASL/GSSAPI bind.

CVE-2021-3652 [MEDIUM] CWE-287 CVE-2021-3652: A flaw was found in 389-ds-base. If an asterisk is imported as password hashes, either accidentally 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.
