Top vulnerabilities
CVE-2008-2928Multiple 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-2008-0892The 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-2026-9064A flaw was found in 389-ds-base. The get_ldapmessage_controls_ext() function in the LDAP server does not enforce an upper bound on the number of controls per LDAP message. A remote, unauthenticated attacker can send a specially crafted LDAP request containing hundreds of thousands of minimal controls within the default maximum BER message size (2 MB), causing excessive CPU consumption and heap allocation on the server. Under concurrent exploitation, this leads to significant latency degradation, worker thread starvation, or out-of-memory termination, resulting in a denial of service.
CVE-2026-11788A 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-2014-3562Red Hat Directory Server 8 and 389 Directory Server, when debugging is enabled, allows remote attackers to obtain sensitive replicated metadata by searching the directory.
CVE-2010-2222The _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-2008-1677Buffer 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-2022-1949An 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-2008-0890Red Hat Directory Server 7.1 before SP4 uses insecure permissions for certain directories, which allows local users to modify JAR files and execute arbitrary code via unknown vectors.
CVE-2008-0889Red Hat Directory Server 8.0, when running on Red Hat Enterprise Linux, uses insecure permissions for the redhat-idm-console script, which allows local users to execute arbitrary code by modifying the script.
CVE-2026-11789A flaw was found in 389 Directory Server. The SMD5 password storage plugin performs unsigned integer underflow when computing salt length from a crafted password hash shorter than 16 bytes, causing a buffer over-read that crashes the LDAP server during authentication.
CVE-2026-11786A flaw was found in 389 Directory Server. The LDIF parser reads past the end of a heap buffer when processing attribute types with trailing semicolons during database import, causing an out-of-bounds read detectable under memory instrumentation.
CVE-2026-11611A flaw was found in 389 Directory Server. The Content Synchronization persistent search plugin allows unbounded memory growth when an authenticated client stops reading sync responses, enabling denial of service. Additional race conditions in plugin thread lifecycle can cause crashes during connection teardown or shutdown.
CVE-2024-6237A 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-2022-2850A 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-2026-11787A flaw was found in 389 Directory Server. The ldap_utf8prev() function reads bytes before the start of a buffer without bounds checking, causing a heap buffer over-read in string filter parsing that may influence internal filter processing behavior.
CVE-2011-0532The (1) backup and restore scripts, (2) main initialization script, and (3) ldap-agent script in 389 Directory Server 1.2.x (aka Red Hat Directory Server 8.2.x) place a zero-length directory name in the LD_LIBRARY_PATH, which allows local users to gain privileges via a Trojan horse shared library in the current working directory.
CVE-2008-0893Red Hat Administration Server, as used by Red Hat Directory Server 8.0 EL4 and EL5, does not properly restrict access to CGI scripts, which allows remote attackers to perform administrative actions.
CVE-2024-1062A 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-2023-1055A 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-2020-35518When 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-2013-4485389 Directory Server 1.2.11.15 (aka Red Hat Directory Server before 8.2.11-14) allows remote authenticated users to cause a denial of service (crash) via multiple @ characters in a GER attribute list in a search request.
CVE-2026-11790A flaw was found in 389 Directory Server. The PBKDF2-SHA256 password storage plugin does not enforce an upper bound on the iteration count extracted from stored password hashes. A privileged attacker who can modify a user's password hash can cause excessive CPU consumption during authentication, resulting in denial of service.
CVE-2011-0022The setup scripts in 389 Directory Server 1.2.x (aka Red Hat Directory Server 8.2.x), when multiple unprivileged instances are configured, use 0777 permissions for the /var/run/dirsrv directory, which allows local users to cause a denial of service (daemon outage or arbitrary process termination) by replacing PID files contained in this directory.
CVE-2010-2241The (1) setup-ds.pl and (2) setup-ds-admin.pl setup scripts for Red Hat Directory Server 8 before 8.2 use world-readable permissions when creating cache files, which allows local users to obtain sensitive information including passwords for Directory and Administration Server administrative accounts.
