Doc Text:
A flaw was found in iperf3. A malformed Base64-encoded authentication string triggers an assertion failure within the `iperf_auth.c` file, leading to application termination. This vulnerability allows a network attacker to induce this failure by sending a crafted authentication attempt, resulting in an application-level denial of service condition.
