printf vulnerable to Regular Expression Denial of Service (ReDoS)
The package printf before 0.6.1 are vulnerable to Regular Expression Denial of Service (ReDoS) via the regex string
/\%(?:\(([\w_.]+)\)|([1-9]\d*)\$)?([0 +\-\]*)(\*|\d+)?(\.)?(\*|\d+)?[hlL]?([\%bscdeEfFgGioOuxX])/g
in lib/printf.js. The vulnerable regular expression has cubic worst-case time complexity.
