    Package        : ruby-kramdown
    CVE ID         : CVE-2020-14001
    Debian Bug     : 965305
    
    A flaw was discovered in ruby-kramdown, a fast, pure ruby, Markdown
    parser and converter, which could result in unintended read access to
    files or unintended embedded Ruby code execution when the {::options /}
    extension is used together with the 'template' option.
    
    The Update introduces a new option 'forbidden_inline_options' to
    restrict the options allowed with the {::options /} extension. By
    default the 'template' option is forbidden.
    
    For the stable distribution (buster), this problem has been fixed in
    version 1.17.0-1+deb10u1.
    
    We recommend that you upgrade your ruby-kramdown packages.
    
    For the detailed security status of ruby-kramdown please refer to its
    security tracker page at:
