    CVE ID         : CVE-2022-29970 CVE-2022-45442
    Debian Bug     : 1014717 1070953

    Sinatra is an open source web framework for Ruby programming language.

    CVE-2022-29970

        A file traversal vulnerability was discovered. We now validate that
        any expanded paths match the allowed `public_dir` when serving
        static files.

    CVE-2022-45442

        It was discovered that there was a potential reflected file download
        (RFD) vulnerability. A Content-Disposition HTTP header was being
        incorrectly derived from a potentially user-supplied filename.

    For Debian 11 bullseye, these problems have been fixed in version
    2.0.8.1-2+deb11u1.

    We recommend that you upgrade your ruby-sinatra packages.
