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.
