There is a defect in the CPython “tarfile” module affecting the
“TarFile” extraction and entry enumeration APIs. The tar implementation
would process tar archives with negative offsets without error,
resulting in an infinite loop and deadlock during the parsing of
maliciously crafted tar archives. This vulnerability can be mitigated
by including the following patch after importing the “tarfile” module:

There are two "new" CVEs reported for python3, their CPEs are:
* CVE-2020-1171: cpe:2.3🅰️microsoft:python:*:*:*:*:*:visual_studio_code:*:* (< 2020.5.0)
* CVE-2020-1192: cpe:2.3🅰️microsoft:python:*:*:*:*:*:visual_studio_code:*:* (< 2020.5.0)
These are for "Visual Studio Code Python extension".
Solve this by addding CVE vendor to python CVE product to avoid
confusion with Microsoft as vendor.
Examining CVE DB for historical python entries shows:
sqlite> select vendor, product, count(*) from products where product = 'python' or product = 'cpython'
...> or product like 'python%3' group by vendor, product;
microsoft|python|2
python|python|1054
python_software_foundation|python|2
Note that this already shows that cpython product is not used, so
CVE-2023-33595 mentioned in 62598e1138f21a16d8b1cdd1cfe902aeed854c5c
was updated.
But let's keep it for future in case new CVE starts with that again.
