CVE-2017-16021 Information

Description

uri-js is a module that tries to fully implement RFC 3986. One of these features is validating whether or not a supplied URL is valid or not. To do this uri-js uses a regular expression This regular expression is vulnerable to redos. This causes the program to hang and the CPU to idle at 100 usage while uri-js is trying to validate if the supplied URL is valid or not. To check if you’re vulnerable look for a call to require(\uri-js\).parse() where a user is able to send their own input. This affects uri-js 2.1.1 and earlier.
