OpenLDAP SASL authcid Name BIND Request DoS

Medium Nessus Plugin ID 23625


The remote LDAP server is prone to a denial of service attack.


The remote host appears to be running OpenLDAP, an open source LDAP directory implementation.

The version of OpenLDAP installed on the remote host fails to handle malformed SASL bind requests. An unauthenticated attacker can leverage this issue to crash the LDAP server on the affected host.


Upgrade to OpenLDAP 2.3.29 or later.
