Description

OwnTone Server versions 28.4 through 29.0 contain a race condition vulnerability in the DAAP login handler that allows unauthenticated attackers to crash the server by exploiting unsynchronized access to the global DAAP session list. Attackers can flood the DAAP /login endpoint with concurrent requests to trigger a remote denial of service condition without requiring authentication.

CWE-362

Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently.
