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') •

The overflow protection in Expat is removed by compilers with certain optimization settings, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted XML data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1283 and CVE-2015-2716. La protección de desbordamiento en Expat es eliminada por los compiladores con ciertos ajustes de optimización, lo que permite a atacantes remotos provocar una denegación de servicio (caída) o posiblemente ejecutar código arbitrario a través de datos XML manipulados.

CVSS: 9.8EPSS: 0%CPEs: 26EXPL: 0CVE-2016-0718 – expat: Out-of-bounds heap read on crafted input causing crash
https://notcve.org/view.php?id=CVE-2016-0718
Expat allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a malformed input document, which triggers a buffer overflow. Expat permite a atacantes dependientes del contexto provocar una denegación de servicio (caída) o posiblemente ejecutar código arbitrario a través de un documento de entrada mal formado, lo que desencadena un desbordamiento de buffer. An out-of-bounds read flaw was found in the way Expat processed certain input. A remote attacker could send specially crafted XML that, when parsed by an application using the Expat library, would cause that application to crash or, possibly, execute arbitrary code with the permission of the user running the application. • http://lists.apple.com/archives/security-announce/2016/Jul/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2016-08 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
