Description

This module exploits a Regular Expression Denial of Service vulnerability
in the npm module "ua-parser-js". Server-side applications that use
"ua-parser-js" for parsing the browser user-agent string will be vulnerable
if they call the "getOS" or "getResult" functions. This vulnerability was
fixed as of version 0.7.16.
