Bumps redcarpet from 3.4.0 to 3.5.1.

Release notes

Sourced from redcarpet's releases.

Redcarpet v3.5.1

Fix a security vulnerability using :quote in combination with the :escape_html option.

Reported by Johan Smits.

v3.5.0

This release mostly ships with bug fixes and tiny improvements.

Improvements

  • Avoid mutating the options hash passed to a render object (See #663).

  • Automatically enable the fenced_code_blocks option passing a HTML_TOC object to the Markdown object's constructor since some languages rely on the sharp to comment code (See #451).

  • Remove the rel and rev attributes from the output generated for footnotes as they don't pass the HTML 5 validation (See #536).

  • Allow passing Range objects to the nesting_level option to have a higher level of customization for table of contents (See #519):

    Redcarpet::Render::HTML_TOC.new(nesting_level: 2..5)

Bug fixes

  • Fix a segfault rendering quotes using StripDown and the :quote option.

  • Fix SmartyPants single quotes right after a link. For example:

    [John](http://john.doe)'s cat

    Will now properly converts ' to a right single quote (i.e. ).

We've just been alerted that this update fixes a security vulnerability:

Sourced from The GitHub Security Advisory Database.

Injection/XSS in Redcarpet
Redcarpet is a Ruby library for Markdown processing. In Redcarpet before version 3.5.1, there is an injection vulnerability which can enable a cross-site scripting attack. In affected versions no HTML escaping was being performed when processing quotes. This applies even when the :escape_html option was being used. This is fixed in version 3.5.1 by the referenced commit.

Affected versions: ["< 3.5.1"]
