Debian LTS: DLA-4007-1 python-tornado critical redirect issue

CVE-2023-28370

An open redirect vulnerability in Tornado versions 6.3.1 and earlier allows
a remote unauthenticated attacker to redirect a user to an arbitrary web
site and conduct a phishing attack by having the user access a specially
crafted URL.

CVE-2024-52804

The algorithm used for parsing HTTP cookies in Tornado versions prior to
6.4.2 sometimes has quadratic complexity, leading to excessive CPU
consumption when parsing maliciously-crafted cookie headers. This
parsing occurs in the event loop thread and may block the processing of
other requests.

For Debian 11 bullseye, these problems have been fixed in version
6.1.0-1+deb11u1.

We recommend that you upgrade your python-tornado packages.
