    Multiple security issues were discovered in TCPDF, a PHP class for
    generating PDF files on-the-fly, which may result in denial of service,
    cross-site scripting or information disclosure.

    CVE-2024-22640

        ReDoS (Regular Expression Denial of Service) if parsing an untrusted HTML
        page with a crafted color.

    CVE-2024-22641

        ReDoS (Regular Expression Denial of Service) when parsing a specially
        crafted SVG file.

    CVE-2024-32489

        TCPDF mishandles calls that use HTML syntax.

    CVE-2024-51058

        Local File Inclusion (LFI) vulnerability through the <img> src tag.

    CVE-2024-56519

        setSVGStyles does not sanitize the SVG font-family attribute.

    CVE-2024-56520

        TCPDF, throught its use of tc-lib-pdf-font, mishandles fonts like FontBBox
        for Type 1 and misparses TrueType fonts.

    CVE-2024-56522

        The unserializeTCPDFtag() function doesn't make use of constant-time
        function to compare TCPDF tag hashes.

    CVE-2024-56527

        The Error() function lacks an htmlspecialchars call for the error message.

    For Debian 11 bullseye, these problems have been fixed in version
    6.3.5+dfsg1-1+deb11u1.

    We recommend that you upgrade your tcpdf packages.
