Vendor: curl.haxx.se
Description
The vulnerability allows a remote attacker to bypass OCSP verification.
The vulnerability exists due to curl inadvertently keeps the SSL session ID for connections in its cache even when the verify status (OCSP stapling)
test has failed. A subsequent transfer to the same hostname will be successful if the session ID cache is still fresh, which leads to skipping the
verify status check. As a result, OCSP verification is always successful for all subsequent TLS sessions.
Mitigation
Install updates from vendor's website.
