The RecursiveDescentParser and SteppingRecursiveDescentParser components in NLTK can be exploited by crafted ambiguous or left-recursive grammars to cause unbounded CPU consumption or stack exhaustion, resulting in denial of service. This affects applications that parse grammars or inputs from untrusted sources. There is no impact on confidentiality or integrity, only on availability of the affected process. A patch is available to address this issue.
