    Published: 6 Aug 2013Last Modified: 10 Jun 2026

    Summary:

    Details: easy_install in setuptools before 0.7 uses HTTP to retrieve packages from the PyPI repository, and does not perform integrity checks on package contents, which allows man-in-the-middle attackers to execute arbitrary code via a crafted response to the default use of the product.
