Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Parsing pathological type comments can trigger unhandled RecursionError or MemoryError exceptions within the underlying parser module, completely halting the AST generation process. Developers should ensure parsing operations on external inputs are wrapped in defensive try-except blocks.
Denial of Service: Generating string or pretty-print representations of AST nodes containing extremely large integers or oversized identifiers raises unhandled ValueError exceptions during formatting, leading to denial of service during code analysis.
