Description (CNA)
HFS2 version 2.4.0 and earlier contains a denial of service vulnerability that allows unauthenticated attackers to cause a complete and persistent loss of availability by sending a single crafted request. Attackers can trigger a hung serving thread that enters a busy loop, rendering the entire file server unresponsive to all clients without self-recovery until an operator manually restarts the service.
