Description

This module exploits a Denial of Service (DoS) condition in Action View that requires
a controller action. By sending a specially crafted content-type header to a Rails
application, it is possible for it to store the invalid MIME type, and may eventually
consume all memory if enough invalid MIMEs are given.

Versions 3.0.0 and other later versions are affected, fixed in 4.0.2 and 3.2.16.
