If you want a safe alternative, try Unblob https://unblob.org!
Our researcher Quentin fixed these vulnerabilities very early on, even in external tools:
He even found a problem with Python standard library tarfile!
We forked extraction tools we use in Unblob just to be able to fix these path traversal vulnerabilities!
