    Package        : cups-filters
    CVE ID         : CVE-2024-47076 CVE-2024-47176
    Debian Bug     : 1082820 1082827

    Simone Margaritelli reported several vulnerabilities in cups-filters.
    Missing validation of IPP attributes returned from an IPP server and
    multiple bugs in the cups-browsed component can result in the execution
    of arbitrary commands without authentication when a print job is
    started.

    For the stable distribution (bookworm), these problems have been fixed in
    version 1.28.17-3+deb12u1.

    We recommend that you upgrade your cups-filters packages.

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