A flaw was found in NLTK. This uncontrolled recursion vulnerability in `nltk.featstruct.FeatStructReader` allows unauthenticated attackers to cause a denial of service. Attackers can achieve this by supplying deeply nested feature-structure input, which can lead to applications crashing when parsing user-supplied feature structures or feature grammars.
