CVE-2017-12625: Apache Hive information disclosure vulnerability for column 

Severity: Important

Vendor: The Apache Software Foundation

Versions Affected: Hive 2.1.0 to 2.3.0


Hive exposes an interface through which masking policies can be defined on 
tables or views, e.g., using Apache Ranger. When a view is created over a 
given table, the policy enforcement does not happen correctly on the table for
masked columns.


2.3.0 users should upgrade to 2.3.1

2.2.0 users should upgrade to 2.3.1, obtain the latest source from git for 

or apply this patch which will be included from 2.2.1;a=3Dcommit;h=3D0e795debddf261b0ac6ace90e2d774f9a99b7f4b

2.1.x users should upgrade to 2.3.1, obtain the latest source from git for 

or apply this patch which will be included from 2.1.2;a=3Dcommit;h=3D6db9fd6e43f6eef3c9d1ca8e324b2edaa54fb0d3

To mitigate this vulnerability until Hive is upgraded to a new version, there
are two possible options. These steps need to be done manually in Ranger / 

1) Restrict users from creating views on tables with column masking rules 
defined. For

this in Ranger Hive Policy:

 - Users should not have SELECT permission for those Table columns with 
masking rules defined.

 - Give SELECT permission only for those columns without masking rules 

2) Review the Hive Column Masking Policies maintained in Ranger for the 
tables. Then check in Hive if views that read those tables have been defined.

If present, either change the view definition so those columns are not 
selected or directly drop those views.
