Debian: DSA-4714-2 Update Addresses High CPU Load in Chromium

The previous update for chromium released as DSA 4714-1 was mistakenly
built without compiler optimizations. This caused high CPU load and
frequent crashes. Updated chromium packages are now available that
correct this issue.

For the oldstable distribution (stretch), security support for chromium
has been discontinued.

For the stable distribution (buster), this problem has been fixed in
version 83.0.4103.116-1~deb10u2.

We recommend that you upgrade your chromium packages.

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