Medium: curl

Issue Overview: A flaw was found in libcurl from versions 7.29.0 through 7.71.1. An application that performs multiple requests with libcurl's multi API, and sets the CURLOPTCONNECTONLY option, might experience libcurl using the wrong connection. The highest threat from this vulnerability is to...

curl: Inferior OCSP verification

Libcurl offers "OCSP stapling" via the CURLOPTSSLVERIFYSTATUS option. When set, libcurl verifies the OCSP response that a server responds with as part of the TLS handshake. It then aborts the TLS negotiation if something is wrong with the response. The same feature can be enabled with --cert-stat...
