CVE-2018-20834

A vulnerability was found in node-tar before version 4.4.2 (excluding
version 2.2.2). An Arbitrary File Overwrite issue exists when extracting a
tarball containing a hardlink to a file that already exists on the system,
in conjunction with a later plain file with the same name as the hardlink.
This plain file content replaces the existing file content. A patch has
been applied to node-tar v2.2.2).
