TrellixVulnTeam 7ad3412591 Adding tarfile member sanitization to extractall() (#1709)
Fix a widespread bug named CVE-2007-4559, which is a 15 year old bug
in the Python tarfile package. By using extract() or extractall() on a tarfile
object without sanitizing input, a maliciously crafted .tar file could
perform a directory path traversal attack. This patch essentially checks to
see if all tarfile members will be extracted safely and throws an exception
otherwise.
