Benno Evers commented on MESOS-9810: ------------------------------------ Review: https://reviews.apache.org/r/70748/ > Reject certificate-less ciphers when certificate verification is enabled > ------------------------------------------------------------------------ > > Key: MESOS-9810 > URL: https://issues.apache.org/jira/browse/MESOS-9810 > Project: Mesos > Issue Type: Task > Reporter: Benno Evers > Priority: Major > Labels: foundations > > A TLS server is required by the spec to always send a server certificate, > unless an anonymous cipher is used. > In libprocess, this certificate is verified to be valid and trusted when the > flag LIBPROCESS_VERIFY_CERT is set to true. > However, when an anonymous cipher is used, the server does not present a > certificate, meaning the verification step will not happen. If a TLS server > would be allowed to use such a cipher, it could trivially sidestep the > security provided by certificate verification. > Therefore, we should always reject connections using anonymous ciphers when > certificate verification is enabled. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
