Thanks so much for flagging this issue and opening a PR @TrellixVulnTeam !
At the moment almost all builds are breaking, so this can't be merged as is. Are you in a capacity to get the code in a mergeable state or do you need someone from the Kedro team to take over?

I know @TrellixVulnTeam added this exception message, but I think we can make it a bit clearer. Maybe something like "Failed to safely extract tar file"

Patching CVE-2007-4559
Hi, we are security researchers from the Advanced Research Center at Trellix. We have began a campaign to patch a widespread bug named CVE-2007-4559. CVE-2007-4559 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. We found at least one unsantized extractall() in your codebase and are providing a patch for you via pull request. The patch essentially checks to see if all tarfile members will be extracted safely and throws an exception otherwise. We encourage you to use this patch or your own solution to secure against CVE-2007-4559. Further technical information about the vulnerability can be found in this blog.
If you have further questions you may contact us through this projects lead researcher Kasimir Schulz.
