NVD Description
Note: Versions mentioned in the description apply only to the upstream 389-ds-base-snmp package and not the 389-ds-base-snmp package as distributed by Centos.
See How to fix? for Centos:8 relevant fixed versions and status.
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.
