A flaw was found in rubygem-tzinfo. When using the Timezone.get function, it fails to validate time zone identifiers correctly, allowing a new line character input within the identifier. This flaw allows an attacker to use the new line character and write any code, which will be executed within the Ruby process.
Mitigation
As a workaround, the time zone identifier can be validated before passing to TZInfo::Timezone.get by ensuring it matches the regular expression \A[A-Za-z0-9+\-]+(?:/[A-Za-z0-9+\-]+)*\z.
