Lars Francke created RANGER-2708:
------------------------------------
Summary: Ranger public group check uses wrong comparison for
equality
Key: RANGER-2708
URL: https://issues.apache.org/jira/browse/RANGER-2708
Project: Ranger
Issue Type: Bug
Components: Ranger
Reporter: Lars Francke
In {{RangerBizUtil#checkUsrPermForPolicy}} we can find this piece of code:
{code:java}
matchFound = (publicGroupId != null && publicGroupId == permMap.getGroupId())
|| isGroupInList(permMap.getGroupId(), userGroups);
{code}
{{publicGroupId}} and {{permMap.getGroupId()}} are both Long so testing
equality using "{{==}}" is wrong and only works "by accident" or not at all
depending on the JVM.
