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

    For the oldstable distribution (bookworm), these problems have been fixed
    in version 146.0.7680.164-1~deb12u1.

    For the stable distribution (trixie), these problems have been fixed in
    version 146.0.7680.164-1~deb13u1.

    We recommend that you upgrade your chromium packages.

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