    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.

    For the stable distribution (bookworm), these problems have been fixed in
    version 6.6.2+dfsg1-1+deb12u1.

    We recommend that you upgrade your tcpdf packages.

    For the detailed security status of tcpdf please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/tcpdf
