Upstream source description

buildebooks before 0.2.2 contains an OS command injection vulnerability in lib/kindle.js that allows attackers to execute commands by supplying a crafted EPUB file name passed to kindlegen via child_process.exec. Attackers can craft a book project with a malicious front-matter filename or project folder name and kindle: true to execute OS commands as the user running buildebooks.
