> Key: MADLIB-617
> URL: https://issues.apache.org/jira/browse/MADLIB-617
> Project: Apache MADlib
> Issue Type: Bug
> Reporter: Caleb Welton
> Assignee: Jiali Yao
> Priority: Critical
>
> In review of MADlib-567 it became clear that there are some followup tasks to
> clean up the sketch based estimators.
> Currently we pass user supplied bytea fields into the functions and treat the
> contents of that bytea as a pointer that we think we can safely follow. This
> is not safe coding practice and can result in severe security issues.
