Safety vulnerability ID: 37767
The information on this page was manually curated by our Cybersecurity Intelligence Team.
Typed_ast 1.3.0 and 1.3.1 have a handle_keywordonly_args 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. (This issue also affected certain Python 3.8.0-alpha prereleases.) See: CVE-2019-19274.
Latest version: 1.5.5
a fork of Python 2 and 3 ast modules with type comment support
