Multiple 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 (bullseye) the updates need an additional
toolchain update. When completed, fixes will be made available as

For the stable distribution (bookworm), these problems have been fixed in
version 118.0.5993.70-1~deb12u1.
