I've tested Lars's patch against my collection of sly tarballs:
https://github.com/jwilk/path-traversal-samples

SafeTarFile defeated most, but not all attacks.
It still allows directory traversal for these two tarfile:

1) https://github.com/jwilk/path-traversal-samples/releases/download/0/dirsymlink2a.tar

lrwxrwxrwx  cur -> .
lrwxrwxrwx  par -> cur/..
-rw-r--r--  par/moo

2) https://github.com/jwilk/path-traversal-samples/releases/download/0/dirsymlink2b.tar

lrwxrwxrwx  cur -> .
lrwxrwxrwx  cur/par -> ..
-rw-r--r--  par/moo
