    Package        : cups
    Version        : 2.2.10-6+deb10u10
    CVE ID         : CVE-2024-35235


    An issue has been found in cups, the Common UNIX Printing System(tm).
    When starting the cupsd server with a Listen configuration item pointing
    to a symbolic link, the cupsd process can be caused to perform an
    arbitrary chmod of the provided argument, providing world-writable access
    to the target.



    For Debian 10 buster, this problem has been fixed in version
    2.2.10-6+deb10u10.

    We recommend that you upgrade your cups packages.

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