summary 
ReDoS
The programming library UA-Parser uses regular expressions to identify user agent strings. The complexity of the regular expressions is such that an attacker can craft special patterns that keep the server busy for a long time. By sending many requests in short order, an attacker can exhaust the amount of processing power available.
