A flaw was found in stunnel before 5.57 where it improperly validates client certificates when it is configured to use both redirect and verifyChain options. This flaw allows an attacker with a certificate signed by a Certificate Authority which is not the one accepted by the stunnel server to access the tunneled service instead of being redirected to the address specified in the redirect option. The highest threat from this vulnerability is to confidentiality.

libcurl-using applications can ask for a specific client certificate to be used in a transfer. This is done with the `CURLOPT_SSLCERT` option (`--cert` with the command line tool).When libcurl is built to use the macOS native TLS library Secure Transport an application can ask for the client certificate by name or with a file name - using the same option. If the name exists as a file it will be used instead of by name.If the appliction runs with a current working directory that is writable by other users (like `/tmp`) a malicious user can create a file name with the same name as the app wants to use by name and thereby trick the application to use the file based cert instead of the one referred to by name making libcurl send the wrong client certificate in the TLS connection handshake.
