CVE-2024-0853

MEDIUM5.3

OCSP verification bypass with TLS session reuse

Published Feb 3, 2024

Modified 7 months ago

Details

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.
