Apache Axis 1.x up to and including 1.4 is vulnerable to a cross-site scripting (XSS) attack in the default servlet/services.

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.

389-ds-base before versions 1.4.0.10, 1.3.8.3 is vulnerable to a race condition in the way 389-ds-base handles persistent search, resulting in a crash if the server is under load. An anonymous attacker could use this flaw to trigger a denial of service.

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.

389 Directory Server before 1.3.3.10 allows attackers to bypass intended access restrictions and modify directory entries via a crafted ldapmodrdn call.

Red Hat Directory Server 8 and 389 Directory Server, when debugging is enabled, allows remote attackers to obtain sensitive replicated metadata by searching the directory.

IBM GSKit 7.x before 7.0.4.48 and 8.x before 8.0.50.16, as used in IBM Security Directory Server (ISDS) and Tivoli Directory Server (TDS), allows remote attackers to cause a denial of service (application crash or hang) via a malformed X.509 certificate chain.

389 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.

Microsoft Active Directory Lightweight Directory Service (AD LDS) on Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, and Windows 8 and Active Directory Services on Windows Server 2008 SP2 and R2 SP1 and Server 2012 allow remote attackers to cause a denial of service (LDAP directory-service outage) via a crafted LDAP query, aka "Remote Anonymous DoS Vulnerability."

The Red Hat Directory Server before 8.2.11-13 and 389 Directory Server do not properly restrict access to entity attributes, which allows remote authenticated users to obtain sensitive information via a search query for the attribute.
