The problem is fixed from the security point of view.

I just noticed that gulp-untar@0.0.7 requires tar@2.2.2,
but we override it to 7.5.7

2.2.2 => 7.5.7 = too big difference = some risk

At the same time gulp-untar@0.0.7 was published 8 years ago, so no chance to get it updated to fix the problem. So, only replacing gulp-untar by another dependency could be an alternative solution...

one possible solution might be to use https://www.npmjs.com/package/gulp-decompress

@sbouchet
I haven’t looked into this in depth and I’m not sure how many changes are needed, so I’ll rely on your expertise.

npm audit says :

tar  <7.5.8
Severity: high
Arbitrary File Read/Write via Hardlink Target Escape Through Symlink Chain in node-tar Extraction - https://github.com/advisories/GHSA-83g3-92jg-28cx
fix available via `npm audit fix --force`
Will install @vscode/sqlite3@5.1.12-vscode, which is a breaking change
node_modules/tar
  @vscode/sqlite3  5.1.2-vscode || 5.1.3-vscode - 5.1.11-vscode
  Depends on vulnerable versions of tar
  node_modules/@vscode/sqlite3

so i'll rework this PR to bump to at least 7.5.8
advisory GHSA-83g3-92jg-28cx
