    Package        : python-tornado
    CVE ID         : CVE-2025-67724 CVE-2025-67725 CVE-2025-67726

    Multiple security vulnerabilities were discovered in the Tornado Python
    web framework, which could result in denial of service, header injection
    or cross-site scripting.

    For the oldstable distribution (bookworm), this problem has been fixed
    in version 6.2.0-3+deb12u4.

    For the stable distribution (trixie), this problem has been fixed in
    version 6.4.2-3+deb13u2.

    We recommend that you upgrade your python-tornado packages.

    For the detailed security status of python-tornado please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/python-tornado
