The following vulnerability was published for 389-ds-base.

| In 389-ds-base up to version, 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.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
