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') •

https://notcve.org/view.php?id=CVE-2017-1000158
CPython (aka Python) up to 2.7.13 is vulnerable to an integer overflow in the PyString_DecodeEscape function in stringobject.c, resulting in heap-based buffer overflow (and possible arbitrary code execution) CPython (también conocido como Python) hasta la versión 2.7.13 es vulnerable a un desbordamiento de enteros en la función PyString_DecodeEscape en stringobject.c, lo que resulta en un desbordamiento de búfer basado en memoria dinámica (heap) y, posiblemente, la ejecución de código arbitrario. • http://www.securitytracker.com/id/1039890 https://bugs.python.org/issue30657 https://lists.debian.org/debian-lts-announce/2017/11/msg00035.html https://lists.debian.org/debian-lts-announce/2017/11/msg00036.html https://lists.debian.org/debian-lts-announce/2018/09/msg00030.html https://lists.debian.org/debian-lts-announce/2018/09/msg00031.html https://security.gentoo.org/glsa/201805-02 https://security.netapp.com/advisory/ntap-20230216-0001 https://www.debian.org/security/2018/ • CWE-190: Integer Overflow or Wraparound •

CVE-2016-5636 – python: Heap overflow in zipimporter module
https://notcve.org/view.php?id=CVE-2016-5636
Integer overflow in the get_data function in zipimport.c in CPython (aka Python) before 2.7.12, 3.x before 3.4.5, and 3.5.x before 3.5.2 allows remote attackers to have unspecified impact via a negative data size value, which triggers a heap-based buffer overflow. Desbordamiento de entero en la función get_data en zipimport.c en CPython (también conocido como Python) en versiones anteriores a 2.7.12, 3.x en versiones anteriores a 3.4.5 y 3.5.x en versiones anteriores a 3.5.2 permite a atacantes remotos tener impacto no especificado a través de un valor de tamaño de datos negativo, lo que desencadena un desbordamiento de búfer basado en memoria dinámica. A vulnerability was discovered in Python, in the built-in zipimporter. A specially crafted zip file placed in a module path such that it would be loaded by a later "import" statement could cause a heap overflow, leading to arbitrary code execution. • https://github.com/insuyun/CVE-2016-5636 http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html http://rhn.redhat.com/errata/RHSA-2016-2586.html http://www.openwall.com/lists/oss-security/2016/06/15/15 http://www.openwall.com/lists/oss-security/2016/06/16/1 http://www.oracle.com/technetwork/topics/security/bulletinjul2016-3090568.html http://www.securityfocus.com/bid/91247 http://www.securitytracker.com/id/1038138 http://www.splunk.com/view/SP-CAAAP • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •

CVE-2016-5699 – python: http protocol steam injection attack
https://notcve.org/view.php?id=CVE-2016-5699
CRLF injection vulnerability in the HTTPConnection.putheader function in urllib2 and urllib in CPython (aka Python) before 2.7.10 and 3.x before 3.4.4 allows remote attackers to inject arbitrary HTTP headers via CRLF sequences in a URL. Vulnerabilidad de inyección CRLF en la función HTTPConnection.putheader en urllib2 y urllib en CPython (también conocido como Python) en versiones anteriores a 2.7.10 y 3.x en versiones anteriores a 3.4.4 permite a atacantes remotos inyectar cabeceras HTTP arbitrarias a través de secuencias CRLF en una URL. It was found that the Python's httplib library (used by urllib, urllib2 and others) did not properly check HTTPConnection.putheader() function arguments. An attacker could use this flaw to inject additional headers in a Python application that allowed user provided header names or values. • https://github.com/bunseokbot/CVE-2016-5699-poc http://blog.blindspotsecurity.com/2016/06/advisory-http-header-injection-in.html http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html http://rhn.redhat.com/errata/RHSA-2016-1626.html http://rhn.redhat.com/errata/RHSA-2016-1627.html http://rhn.redhat.com/errata/RHSA-2016-1628.html http://rhn.redhat.com/errata/RHSA-2016-1629.html http://rhn.redhat.com/errata/RHSA-2016-1630.html http://www.openwall.com • CWE-20: Improper Input Validation CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') •

CVE-2016-0772 – Python smtplib 2.7.11 / 3.4.4 / 3.5.1 - Man In The Middle StartTLS Stripping
https://notcve.org/view.php?id=CVE-2016-0772
The smtplib library in CPython (aka Python) before 2.7.12, 3.x before 3.4.5, and 3.5.x before 3.5.2 does not return an error when StartTLS fails, which might allow man-in-the-middle attackers to bypass the TLS protections by leveraging a network position between the client and the registry to block the StartTLS command, aka a "StartTLS stripping attack." La librería smtplib en CPython (también conocido como Python) en versiones anteriores a 2.7.12, 3.x en versiones anteriores a 3.4.5 y 3.5.x en versiones anteriores a 3.5.2 no devuelve un error cuando StartTLS falla, lo que podría permitir a atacantes man-in-the-middle eludir las protecciones TLS mediante el aprovechamiento de una posición de red entre el cliente y el registro para bloquear el comando StartTLS, también conocido como un "ataque de decapado StartTLS". It was found that Python's smtplib library did not return an exception when StartTLS failed to be established in the SMTP.starttls() function. A man in the middle attacker could strip out the STARTTLS command without generating an exception on the Python SMTP client application, preventing the establishment of the TLS layer. • https://www.exploit-db.com/exploits/43500 http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html http://rhn.redhat.com/errata/RHSA-2016-1626.html http://rhn.redhat.com/errata/RHSA-2016-1627.html http://rhn.redhat.com/errata/RHSA-2016-1628.html http://rhn.redhat.com/errata/RHSA-2016-1629.html http://rhn.redhat.com/errata/RHSA-2016-1630.html http://www.openwall.com/lists/oss-security/2016/06/14/9 http://www.securityfocus.com/bid/91225 http:& • CWE-693: Protection Mechanism Failure •
