Affected of this project `lyft/mapper` are vulnerable to Directory Traversal. `TZInfo::Timezone.get` fails to validate time zone identifiers correctly, allowing a new line character within the identifier. With Ruby version 1.9.3 and later, TZInfo::Timezone.get can be made to load unintended files with require, executing them within the Ruby process. that allows file uploads and has a time zone selector that accepts arbitrary time zone identifiers.
```js
raise InvalidTimezoneIdentifier, 'Invalid identifier' if identifier !~ /^[A-Za-z0-9\+\-_]+(\/[A-Za-z0-9\+\-_]+)*$/
assert_raises(InvalidTimezoneIdentifier) { Timezone.get('../Definitions/UTC') }
