389: denial of service when using certificate groups

The acllas__handle_group_entry function in servers/plugins/acl/acllas.c in 389 Directory Server before 1.2.10 does not properly handled access control instructions (ACIs) that use certificate groups, which allows remote authenticated LDAP users with a certificate group to cause a denial of service (infinite loop and CPU consumption) by binding to the server.

rhds/389: plaintext password disclosure flaw

389 Directory Server before 1.2.11.6 (aka Red Hat Directory Server before 8.2.10-3), after the password for a LDAP user has been changed and before the server has been reset, allows remote attackers to read the plaintext password via the unhashed#user#password attribute.

rhds/389: plaintext password disclosure in audit log

389 Directory Server before 1.2.11.6 (aka Red Hat Directory Server before 8.2.10-3), when the password of a LDAP user has been changed and audit logging is enabled, saves the new password to the log in plain text, which allows remote authenticated users to read the password.

389-ds-base: Read permission check bypass via the deref plugin

A flaw was found in the 'deref' plugin of 389-ds-base where it could use the 'search' permission to display attribute values. In some configurations, this could allow an authenticated attacker to view private attributes, such as password hashes.

389-ds-base: access control bypass by query (filter in LDAP terms) optimiser

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 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.

389-ds-base: DoS via hanging secured connections

In 389-ds-base up to version 1.4.1.2, requests are handled by workers threads. Each sockets will be waited by the worker for at most 'ioblocktimeout' seconds. However this timeout applies only for un-encrypted requests. Connections using SSL/TLS are not taking this timeout into account during reads, and may hang longer.An unauthenticated attacker could repeatedly create hanging LDAP requests to hang all the workers, resulting in a Denial of Service.

389-ds-base: using dscreate in verbose mode results in information disclosure

A flaw has been found in 389-ds-base versions 1.4.x.x before 1.4.1.3. When executed in verbose mode, the dscreate and dsconf commands may display sensitive information, such as the Directory Manager password. An attacker, able to see the screen or record the terminal standard error output, could use this flaw to gain sensitive information.

389-ds-base: ns-slapd crash via large filter value in ldapsearch

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-ds-base: replication and the Retro Changelog plugin store plaintext password by default

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.
