Subject: [PATCH 1/2] Add length limit option for methods that parses date
strings
This patch fixes CVE-2021-41817 and created from the commit
<https://github.com/ruby/date/commit/4f9b8e946ba98f0a1774f8e677baa4a45637ebb3>.
We didn't merge the files included in the original commit below, as those are
for rebasing date gem version.
* ext/date/date.gemspec
* ext/date/lib/date.rb
== Original commit message ==
`Date.parse` now raises an ArgumentError when a given date string is
longer than 128. You can configure the limit by giving `limit` keyword
arguments like `Date.parse(str, limit: 1000)`. If you pass `limit: nil`,
the limit is disabled.
Not only `Date.parse` but also the following methods are changed.
* Date._parse
* Date.parse
* DateTime.parse
* Date._iso8601
* Date.iso8601
* DateTime.iso8601
* Date._rfc3339
* Date.rfc3339
* DateTime.rfc3339
* Date._xmlschema
* Date.xmlschema
* DateTime.xmlschema
* Date._rfc2822
* Date.rfc2822

* Date._rfc822
* Date.rfc822
