CVE-2024-0853 · OCSP verification bypass with TLS session reuse

This page contains facts from public vulnerability sources. Check the original advisory before updating.

curl inadvertently kept the SSL session ID for connections in its cache even when the verify status (*OCSP stapling*) test failed. A subsequent transfer to the same hostname could then succeed if the session ID cache was still fresh, which then skipped the verify status check.
