NVD Description

Note: Versions mentioned in the description apply only to the upstream jython package and not the jython package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

Jython 2.2.1 uses the current umask to set the privileges of the class cache files, which allows local users to bypass intended access restrictions via unspecified vectors.
