    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 148.0.7778.167-1~deb12u1.

    For the stable distribution (trixie), these problems have been fixed in     version 148.0.7778.167-1~deb13u1.

    We recommend that you upgrade your chromium packages.
