libreoffice-convert is a Node.js module for converting office documents to different formats. Prior to 1.8.2, index.js uses the caller-controlled options.fileName value in path.join(tempDir.name, fileName) without reducing it to a base name. A filename containing ../ can escape the temporary directory because path.basename() normalization is missing and write the supplied document buffer to an arbitrary path writable by the process, including an SSH authorized_keys file, a cron configuration, or a web root. This issue is fixed in version 1.8.2.
