How to fix?

There is no fixed version for rply.

Overview

rply is a Python parser generator, that also works with RPython.

Affected versions of this package are vulnerable to Improper Validation of Array Index via improper array index validation in ply_read_header_property(), which accepts list as a list property's length or value type. An attacker can supply a PLY file that causes ply_read_list_property() to call an out-of-bounds function pointer handler, crashing ASCII parsing or corrupting memory in binary parsing.
