NVD Description

Note: Versions mentioned in the description apply only to the upstream nemo package and not the nemo package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

NLTK before 3.10.3 contains an uncontrolled recursion vulnerability in nltk.featstruct.FeatStructReader that allows unauthenticated attackers to cause a denial of service by supplying deeply nested feature-structure input. Attackers can craft trivial payloads with nested brackets that exceed Python's recursion limit and raise an unhandled RecursionError, crashing applications that parse user-supplied feature structures or feature grammars.
