Robert Kanter updated HDFS-7274:
--------------------------------
Attachment: HDFS-7274.patch
The patch sets the sslEnabledProtocols to TLSv1,TLSv1.1. I would have also
added TLSv1.2, but Java 6 doesn't support it (we can add it when we drop Java 6
support).
For verification:

> Disable SSLv3 (POODLEbleed vulnerability) in HttpFS
> ---------------------------------------------------
>
> Key: HDFS-7274
> URL: https://issues.apache.org/jira/browse/HDFS-7274
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: webhdfs
> Affects Versions: 2.6.0
> Reporter: Robert Kanter
> Assignee: Robert Kanter
> Priority: Blocker
> Attachments: HDFS-7274.patch
>
>
> We should disable SSLv3 in HttpFS to protect against the POODLEbleed
> vulnerability.
> See
> [CVE-2014-3566|http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-3566]
> We have {{sslProtocol="TLS"}} set to only allow TLS in ssl-server.xml, but
> when I checked, I could still connect with SSLv3. There documentation is
> somewhat unclear in the tomcat configs between {{sslProtocol}},
> {{sslProtocols}}, and {{sslEnabledProtocols}} and what each value they take
> does exactly. From what I can gather, {{sslProtocol="TLS"}} actually
> includes SSLv3 and the only way to fix this is to explicitly list which TLS
> versions we support.
