Summary

In OCaml-TLS before 2.1.0, the client implementation does insufficient checks of the certificate provided by the server, which allows impersonation with certificates that are not meant for server authentication (because of KeyUsage and ExtendedKeyUsage).

Does this affect you?

Add your gear to cvedb and we'll alert you only when a vendor you run ships something exploited.
