Please describe your issue:

asar 1.0.0 now has updated dependencies without which a high level "Arbitrary File Overwrite" vulnerability is present.

The dependency path to this vulnerability is electron-packager > asar > mksnapshot > decompress-zip and it described here: https://www.npmjs.com/advisories/777

asar 1.0.0 was just updated to remove dependency of mksnapshot so the vulnerability is no longer present in the no longer maintained decompress-zip

Yes, I was part of getting asar to 1.0.0. I plan on doing it when I have some free time.

Also, I plan on adding dependabot to this repository, so for future reference to visitors to this repository, issues asking for dependency version updates are not necessary.
