What is CVE-2019-19275?

The typed_ast library versions 1.3.0 and 1.3.1 contain an out-of-bounds read issue within the ast_for_arguments function. This vulnerability arises when a Python interpreter processes Python source code, potentially leading to a crash of the interpreter process without executing the code. Such a scenario can pose challenges for web services that utilize Python code parsing. It is important for users of these specific versions to apply the necessary updates to mitigate potential disruptions.
