Astra Linux – Vulnerability in Python 3.11

When using TarFile.errorlevel = 0 and extracting with a filter, the documented behavior is that any filtered members would be skipped and not extracted. However, the actual behavior of TarFile.errorlevel = 0 in affected versions is that the member will still be extracted and not skipped...

Astra Linux – Vulnerability in python-pip

When extracting a tar archive, pip may not check symbolic links pointing into the extraction directory if the tarfile module does not implement PEP 706. Note that upgrading pip to a “fixed” version does not fix all vulnerabilities that are mitigated by using a Python version that implements PEP...
