Description Andrej Nemec 2017-10-10 09:42:11 UTC 
Fresh is a module used by the Express.js framework for 'HTTP response freshness testing'. It is vulnerable to a regular expression denial of service when it is passed specially crafted input to parse. This causes the event loop to be blocked causing a denial of service condition.
