Eron Wright created FLINK-5030: ----------------------------------- Summary: Support hostname verification Key: FLINK-5030 URL: https://issues.apache.org/jira/browse/FLINK-5030 Project: Flink Issue Type: Sub-task Reporter: Eron Wright
_See [Dangerous Code|http://www.cs.utexas.edu/~shmat/shmat_ccs12.pdf] and [further commentary|https://tersesystems.com/2014/03/23/fixing-hostname-verification/] for useful background._ When hostname verification is performed, it should use the hostname (not IP address) to match the certificate. The current code is wrongly using the address. In technical terms, ensure that calls to `SSLContext::createSSLEngine` supply the expected hostname, not host address. Please audit all SSL setup code as to whether hostname verification is enabled, and file follow-ups where necessary. For example, Akka 2.4 supports it but 2.3 doesn't ([ref|http://doc.akka.io/docs/akka/2.4.4/scala/http/client-side/https-support.html#Hostname_verification]). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
