* [3.11] gh-95778: CVE-2020-10735: Prevent DoS by very large int() (#96500)Gregory P. Smith2022-09-021-0/+13
| | | | | | | | | | | | | | | | | | Integer to and from text conversions via CPython's bignum `int` type is not safe against denial of service attacks due to malicious input. Very large input strings with hundred thousands of digits can consume several CPU seconds. This PR comes fresh from a pile of work done in our private PSRT security response team repo.

| | | | | | | | | | | | | | | This PR is part of PEP 657 and augments the compiler to emit ending line numbers as well as starting and ending columns from the AST into compiled code objects. This allows bytecodes to be correlated to the exact source code ranges that generated them. This information is made available through the following public APIs: * The `co_positions` method on code objects. * The C API function `PyCode_Addr2Location`.
