      node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.18, tar.replace accepts a checksum-valid tar
      header with a negative base-256 encoded entry size, causing the archive scanner to make no progress while repeatedly
      parsing the same header. This issue is fixed in version 7.5.18.
