The mirroring support (-M, --use-mirrors) in Python Pip before 1.5 uses insecure DNS querying and authenticity checks which allows attackers to perform man-in-the-middle attacks. El soporte de duplicación (-M, --use-mirrors) en Python Pip versiones anteriores a la versión 1.5, utiliza consultas DNS no seguras y comprobaciones de autenticidad que permiten a atacantes realizar ataques de tipo man-in-the-middle. • https://www.exploit-db.com/exploits/24086 http://lists.fedoraproject.org/pipermail/package-announce/2015-April/155248.html http://lists.fedoraproject.org/pipermail/package-announce/2015-April/155291.html http://www.openwall.com/lists/oss-security/2013/08/21/17 http://www.openwall.com/lists/oss-security/2013/08/21/18 http://www.securityfocus.com/bid/77520 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2013-5123 https://bugzilla.suse.com/show_bug.cgi?id=CVE-2013-5123 https&# • CWE-287: Improper Authentication •

pip before 1.3 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 a "pip install" operation. “pip” anterior a v1.3 utiliza HTTP para recuperar paquetes del repositorio PyPI, y no realiza comprobaciones de integridad en el contenido del paquete, que permite a atacantes man-in-the-middle ejecutar código arbitrario a través de una respuesta diseñada a una operación de "pip install". • http://www.pip-installer.org/en/latest/installing.html http://www.pip-installer.org/en/latest/news.html#changelog http://www.reddit.com/r/Python/comments/17rfh7/warning_dont_use_pip_in_an_untrusted_network_a https://bugzilla.redhat.com/show_bug.cgi?id=968059 https://github.com/pypa/pip/issues/425 https://github.com/pypa/pip/pull/791/files • CWE-20: Improper Input Validation •
