curl: curl: Man-in-the-middle attack via SSH host key bypass

A flaw was found in curl. When a libcurl-based application uses SCP:// or SFTP:// for transfers and employs the CURLOPTSSHKEYFUNCTION callback, it may silently accept an untrusted server. This occurs if the server's host key type differs from the one stored in the knownhosts file. The callback...
