Debian 10: DSA-5938-1 critical: tornado DoS due to logging

It was discovered that the Tornado Python web framework performed
excessive logging when parsing some multipart/form-data requests, which
could result in denial of service.

For the stable distribution (bookworm), this problem has been fixed in
version 6.2.0-3+deb12u2.

We recommend that you upgrade your python-tornado packages.
