https://notcve.org/view.php?id=CVE-2018-1060
python before versions 2.7.15, 3.4.9, 3.5.6rc1, 3.6.5rc1 and 3.7.0 is vulnerable to catastrophic backtracking in pop3lib's apop() method. An attacker could use this flaw to cause denial of service. Python antes de las versiones 2.7.15, 3.4.9, 3.5.6rc1, 3.6.5rc1 y 3.7.0 es vulnerable a un retroceso catastrófico en el método apop () de pop3lib. Un atacante podría usar este fallo para causar la denegación de servicio. A flaw was found in the way catastrophic backtracking was implemented in python's pop3lib's apop() method. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html http://www.securitytracker.com/id/1042001 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3041 https://access.redhat.com/errata/RHSA-2018:3505 https://access.redhat.com/errata/RHSA-2019:1260 https://access.redhat.com/errata/RHSA-2019:3725 https://bugs.python.org/issue32981 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-1060 https://docs.python.org/ • CWE-20: Improper Input Validation •

CVE-2017-18207
https://notcve.org/view.php?id=CVE-2017-18207
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 •
CVE-2017-17522
https://notcve.org/view.php?id=CVE-2017-17522
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') •
