    CVE ID         : CVE-2024-6290 CVE-2024-6291 CVE-2024-6292 CVE-2024-6293

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

    For the stable distribution (bookworm), these problems have been fixed in
    version 126.0.6478.126-1~deb12u1.

    We recommend that you upgrade your chromium packages.

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

    Further information about Debian Security Advisories, how to apply
    these updates to your system and frequently asked questions can be
