Asymmetric denial of service In curl

Description

By default, curl automatically responds to WebSocket PING frames. Because curl lacks an upper bound on memory allocation for unacknowledged frames, a malicious server can exhaust all available memory by flooding curl with rapid, sequential PING messages.

Mitigation

Update Impact

Minimal update. May introduce new vulnerabilities or breaking changes.
