Technical details
The vulnerability exists in the Simple Authentication and Security Layer (SASL) UNBIND process in 389-ds-base. An authenticated remote attacker can craft a specially designed request that causes a connection to stall, triggering resource exhaustion on the server. This leads to a denial of service condition. Authentication is a precondition—the attacker must first establish a valid authenticated session to exploit this flaw. The attack vector is network-based and does not require user interaction beyond the attacker's ability to send the crafted request.
