Description

A flaw was found in pip. This vulnerability occurs because pip incorrectly processes concatenated tar and ZIP files as ZIP files, regardless of their true format. This improper handling can lead to confusing installation behavior, potentially causing the installation of unintended or 'incorrect' files. This could allow an attacker to influence the installation process by providing a specially crafted archive.
