    Security issues were discovered in Chromium which could result
    in the execution of arbitrary code, denial of service, or information
    disclosure.

    For Debian 12 bookworm, these problems have been fixed in version
    152.0.7977.82-1~deb12u1.

    We recommend that you upgrade your chromium packages.

    For the detailed security status of chromium please refer to
    its security tracker page at:
