Subject [jira] [Commented] (CASSANDRA-9402) Implement proper sandboxing for UDFs
Date Thu, 23 Jul 2015 15:11:05 GMT


T Jake Luciani commented on CASSANDRA-9402:

Overall, This is an improvement.  We spoke offline and addressed a potential issue with user_function_timeout_policy.
 Since a Stop-the-world GC could happen during execution of the UDF.

I'd like to get a professional opinion on this work, since I'm not convinced you couldn't,
for example, access "/etc/password" via Nashorn (since nio is whitelisted).

UDFs with good defaults so someone exposing it to the internet accidentally doesn't open themselves
up to having arbitrary code run.
