summary 
ReDoS Vulnerability in ua-parser-js version
### Description:
A regular expression denial of service (ReDoS) vulnerability has been discovered in `ua-parser-js`.

### Impact:
This vulnerability bypass the library's `MAX_LENGTH` input limit prevention. By crafting a very-very-long user-agent string with specific pattern, an attacker can turn the script to get stuck processing for a very long time which results in a denial of service (DoS) condition.

### Affected Versions:
From version `0.7.30` to before versions `0.7.33` / `1.0.33`.

### Patches:
A patch has been released to remove the vulnerable regular expression, update to version `0.7.33` / `1.0.33` or later.
