{"id":"GHSA-7xxv-wpxj-mx5v","summary":"typed-ast Out-of-bounds Read","details":"typed_ast 1.3.0 and 1.3.1 has an ast_for_arguments out-of-bounds read. An attacker with the ability to cause a Python interpreter to parse Python source (but not necessarily execute it) may be able to crash the interpreter process. This could be a concern, for example, in a web-based service that parses (but does not execute) Python code.
