Description Andrej Nemec 2017-01-12 14:40:49 UTC
Type Confusion exists in two methods of Ruby’s WIN32OLE class, ole_invoke and ole_query_interface. Attacker passing different type of object than this assumed by developers can cause arbitrary code execution.

Comment 1 Andrej Nemec 2017-01-12 14:53:52 UTC
Statement:

This issue did not affect the versions of ruby as shipped with Red Hat Enterprise Linux or Red Hat Software Collections as they did not include support for OLE.
