Vulnerabilities fixed

Sourced from The Ruby Advisory Database.

Path Traversal in Sprockets
Specially crafted requests can be used to access files that exist on
the filesystem that is outside an application's root directory, when the
Sprockets server is used in production.

All users running an affected release should either upgrade or use one of the work arounds immediately.

Workaround:
In Rails applications, work around this issue, set config.assets.compile = false and
config.public_file_server.enabled = true in an initializer and precompile the assets.

Patched versions: >= 2.12.5, < 3.0.0; >= 3.7.2, < 4.0.0; >= 4.0.0.beta8
