Vulnerability details

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled memory consumption in django.utils.translation.check_for_language() when checking many distinct, very long language codes. A remote attacker can send crafted POST data containing many distinct long language values to cause a denial of service.

The language value reaches this function through the django.views.i18n.set_language() view, which is not active by default, and the memory consumption is bounded by request size and cache entry limits.
