    Package        : python-django
    Version        : 2:2.2.28-1~deb11u5
    CVE ID         : CVE-2024-56374
    Debian Bug     : 1093049

    It was discovered that there was potential Denial of Service (DoS)
    vulnerability in Django, the Python-based web development framework.

    The lack of upper-bound limit enforcement in IPv6 validation could
    have led to a potential denial-of-service attack. The undocumented
    and private clean_ipv6_address and is_valid_ipv6_address functions
    were vulnerable, as was the GenericIPAddressField form field.

    For Debian 11 bullseye, this problem has been fixed in version
    2:2.2.28-1~deb11u5.

    We recommend that you upgrade your python-django packages.

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