Heap-based Buffer Overflow vulnerability in iniparser_dumpsection_ini() in iniparser allows attacker to read out of bound memory

iniparser v4.1 is vulnerable to NULL Pointer Dereference in function iniparser_getlongint which misses check NULL for function iniparser_getstring's return.

This affects all versions of package iniparserjs. This vulnerability relates when ini_parser.js is concentrating arrays. Depending on if user input is provided, an attacker can overwrite and pollute the object prototype of a program.
