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: 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.
