    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.
    
    For Debian 9 stretch, this problem has been fixed in version
    3.3.4-2+deb9u1.
    
    We recommend that you upgrade your ruby-redcarpet packages.
