Advisories for Npm/Pdf-Image package

pdf-image (npm package) through version 2.0.0 allows OS command injection via the pdfFilePath parameter. The constructGetInfoCommand and constructConvertCommandForPage functions use util.format() to interpolate user-controlled file paths into shell command strings that are executed via child_process.exec().

A lack of input validation in pdf-image npm package version may allow an attacker to run arbitrary code if PDF file path is constructed based on untrusted user input.

Command injection exists in pdf-image due to an unescaped string parameter.
