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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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. (CVE-2013-1633)

Note that Nessus relies on the presence of the package as reported by the vendor.

python-setuptools so far used only HTTP to retrieve packages, which could have lead to man in the middle attacks on newly installed python code.

This update adjusts it to use HTTPS, guaranteeing better connection integrity.

The remote host is affected by the vulnerability described in GLSA-201310-09 (Setuptools: Man-in-the-Middle attack)

    Setuptools does not check the integrity of downloaded Python packages.
  Impact :

    A remote attacker could perform man-in-the-middle attacks to execute       arbitrary code with the privileges of the process.
  Workaround :

    There is no known workaround at this time.

A vulnerability has been discovered and corrected in python-setuptools/python-virtualenv :

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 (CVE-2013-1633).

The updated python-setuptools packages has been upgraded to the 0.9.8 version and the python-virtualenv packages has been upgraded to the 1.10.1 version which is not vulnerable to this issue.

From upstream :

  - Upgraded pip to v1.4.1

    - Upgraded setuptools to v0.9.8
