CVE-2026-18453 1 Redhat 11 Directory Server, Directory Server E4s, Enterprise Linux and 8 more 2026-11-04 7.5 High
A flaw was found in 389 Directory Server. A missing NULL pointer check in the paged results handling of op_shared_search allows an unauthenticated remote attacker to crash the LDAP server by sending a crafted sequence of search requests using the USE_ONE_BACKEND control, resulting in denial of service.
CVE-2026-15722 1 Redhat 12 389 Directory Server, Directory Server, Directory Server E4s and 9 more 2026-11-04 7.5 High
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 attacker can crash the LDAP server by sending a crafted StartNSDS50ReplicationRequest extended operation containing a replica ID field with more than 16 digit characters. The overflow occurs during payload decoding, before any authorization check. Stack protectors limit impact to denial of service.
CVE-2026-11774 1 Redhat 11 Directory Server, Directory Server E4s, Enterprise Linux and 8 more 2026-11-04 7.6 High
An integer overflow flaw was found in the SASL I/O layer of 389 Directory Server (389-ds-base). In sasl_io_start_packet(), adding sizeof(uint32_t) to a crafted SASL packet length prefix of 0xFFFFFFFC causes unsigned wraparound to zero, bypassing the nsslapd-maxsasliosize limit and leading to a heap buffer overflow of up to approximately 2 megabytes of attacker-controlled data. After a successful SASL bind with integrity protection (SSF > 0), a remote attacker can cause a Denial of Service (DoS) or achieve Remote Code Execution (RCE). In FreeIPA and Red Hat Identity Management deployments, any domain user with a valid Kerberos ticket, enrolled host, or service account can trigger this vulnerability over the network. This flaw is independent of CVE-2025-14905, which patched schema.c only and did not modify sasl_io.c.
CVE-2026-18922 1 Redhat 11 Directory Server, Directory Server E4s, Enterprise Linux and 8 more 2026-10-08 9.8 Critical
A flaw was found in 389 Directory Server. During SASL PLAIN authentication, a stale identity carried in a Cyrus SASL auxiliary property from a prior failed bind attempt can be installed on a connection following a subsequent, unrelated successful bind, regardless of which SASL mechanism completes that second bind. An attacker can send a SASL PLAIN bind as cn=Directory Manager with an incorrect password, then complete a SASL ANONYMOUS bind on the same connection, causing the server to grant Directory Manager authority without any valid credentials. A variant using a valid low-privileged account's own successful bind instead of an anonymous one is also possible.
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.
