-----------------------------------
Summary: 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
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.
