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 •

An issue was discovered in markdown2 (aka python-markdown2) through 2.3.5. The safe_mode feature, which is supposed to sanitize user input against XSS, is flawed and does not escape the input properly. With a crafted payload, XSS can be triggered, as demonstrated by omitting the final '>' character from an IMG tag. Se ha descubierto un problema en markdown2 (también conocido como python-markdown2) hasta la versión 2.3.5. La característica safe_mode, que se supone que sanear entradas contra XSS, tiene errores y no escapa las entradas correctamente. • https://github.com/trentm/python-markdown2/issues/285 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

Lib/webbrowser.py in Python through 3.6.3 does not validate strings before launching the program specified by the BROWSER environment variable, which might allow remote attackers to conduct argument-injection attacks via a crafted URL. NOTE: a software maintainer indicates that exploitation is impossible because the code relies on subprocess.Popen and the default shell=False setting ** EN DISPUTA ** Lib/webbrowser.py en Python hasta la versión 3.6.3 no valida las cadenas antes de iniciar el programa especificado por la variable de entorno BROWSER. Esto podría permitir que atacantes remotos lleven a cabo ataques de inyección de argumentos mediante una URL manipulada. NOTA: el mantenedor del software indica que es imposible la explotación de esta vulnerabilidad debido a que el código confía en subprocess.Popen y el ajuste por defecto shell=False. • http://www.securityfocus.com/bid/102207 https://bugs.python.org/issue32367 https://security-tracker.debian.org/tracker/CVE-2017-17522 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
