Description Martin Prpič 2015-11-04 05:16:40 EST
It was found that uglify-js is vulnerable to regular expression denial of service (ReDoS) when certain types of input are passed to the .parse() function.

This could potentially allow a remote attacker to submit a crafted JavaScript code to a service that minifies it using the uglify-js library, and cause that service to consume an excessive amount of CPU.
