Inefficient Regular Expression Complexity

Summary

The parse-duraton is software that allows users to convert a human-readable duration to milliseconds. The parse-duration package versions prior to 2.1.3 are vulnerable to an event loop delay due to the CPU-bound operation of resolving the provided string, from a `0.5ms` and up to `~50ms` per one operation, with a varying size from 0.01 MB and up to 4.3 MB respectively, and an out of memory that would crash a running Node.js application due to a string size of roughly 10 MB that utilizes Unicode characters.
