Python Software Foundation Python (CPython) version 2.7 contains a CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability in shutil module (make_archive function) that can result in Denial of service, Information gain via injection of arbitrary files on the system or entire drive. This attack appear to be exploitable via Passage of unfiltered user input to the function. This vulnerability appears to have been fixed in after commit add531a1e55b0a739b0f42582f1c9747e5649ace. Python Software Foundation Python (CPython) versión 2.7 contiene un CWE-77: neutralización incorrecta de elementos especiales empleados en una vulnerabilidad de comandos ("inyección de comandos") en el módulo shutil (función make_archive) que puede resultar en una denegación de servicio (DoS), la obtención de información mediante la inyección de archivos arbitrarios en el sistema o en todo el disco. El ataque parece ser explotable mediante el paso de entradas de usuario no filtradas a la función. • https://github.com/tna0y/CVE-2018-1000802-PoC http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html https://bugs.python.org/issue34540 https://github.com/python/cpython/pull/8985 https://github.com/python/cpython/pull/8985/commits/add531a1e55b0a739b0f42582f1c9747e5649ace https://lists.debian.org/debian-lts-announce/2018/09/msg00030.html https://lists.debian.org/debian-lts-announce/2018/09/msg00031.html https://mega.nz/#%21JUFiCC4R%21mq-jQ8ySFwIhX6WMDujaZuNBfttDVt7DETlfOIQE1ig https:&#x • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •

The Wave_read._read_fmt_chunk function in Lib/wave.py in Python through 3.6.4 does not ensure a nonzero channel value, which allows attackers to cause a denial of service (divide-by-zero and exception) via a crafted wav format audio file. NOTE: the vendor disputes this issue because Python applications "need to be prepared to handle a wide variety of exceptions. ** EN DISPUTA ** La función Wave_read._read_fmt_chunk en Lib/wave.py en Python, hasta la versión 3.6.4, no garantiza un valor de canal nonzero, lo que permite que atacantes remotos provoquen una denegación de servicio (error de división entre cero y cierre inesperado de la aplicación) mediante un archivo de audio wav manipulado. NOTA: el vendedor informa que las aplicaciones de Python "necesitan estar preparadas para manejar una amplia variedad de excepciones". • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html https://bugs.python.org/issue32056 • CWE-369: Divide By Zero •

Python 2.7.14 is vulnerable to a Heap-Buffer-Overflow as well as a Heap-Use-After-Free. Python versions prior to 2.7.14 may also be vulnerable and it appears that Python 2.7.17 and prior may also be vulnerable however this has not been confirmed. The vulnerability lies when multiply threads are handling large amounts of data. In both cases there is essentially a race condition that occurs. For the Heap-Buffer-Overflow, Thread 2 is creating the size for a buffer, but Thread1 is already writing to the buffer without knowing how much to write. • https://github.com/tylepr96/CVE-2018-1000030 https://bugs.python.org/issue31530 https://drive.google.com/file/d/1oyR9DAZjZK_SCn3mor6NRAYLJS6ueXaY/view https://security.gentoo.org/glsa/201811-02 https://usn.ubuntu.com/3817-1 https://usn.ubuntu.com/3817-2 https://www.dropbox.com/sh/sj3ee7xv55j36k7/AADwP-YfOYikBMuy32e0uvPFa?dl=0 https://www.oracle.com/security-alerts/cpujan2020.html • CWE-416: Use After Free CWE-787: Out-of-bounds Write •
