CVSS: 7.2EPSS: 0%CPEs: 17EXPL: 1CVE-2020-26116 – python: CRLF injection via HTTP request method in httplib/http.client
https://notcve.org/view.php?id=CVE-2020-26116
http.client in Python 3.x before 3.5.10, 3.6.x before 3.6.12, 3.7.x before 3.7.9, and 3.8.x before 3.8.5 allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR and LF control characters in the first argument of HTTPConnection.request. http.client en Python 3.x antes de la versión 3.5.10, 3.6.x antes de la versión 3.6.12, 3.7.x antes de la versión 3.7.9, y 3.8.x antes de la versión 3.8.5 permite la inyección de CRLF si el atacante controla el método de petición HTTP, como se demuestra insertando caracteres de control CR y LF en el primer argumento de HTTPConnection.request A flaw was found in Python. The built-in modules httplib and http.client (included in Python 2 and Python 3, respectively) do not properly validate CRLF sequences in the HTTP request method, potentially allowing manipulation to the request by injecting additional HTTP headers. The highest threat from this vulnerability is to confidentiality and integrity. • http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00027.html https://bugs.python.org/issue39603 https://lists.debian.org/debian-lts-announce/2020/11/msg00032.html https://lists.debian.org/debian-lts-announce/2023/05/msg00024.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BW4GCLQISJCOEGQNIMVUZDQMIY6RR6CC https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HDQ2THWU4GPV4Y5H5WW5PFMSWXL2CRFD https://lists.fedoraproject.org/ • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') •

In Lib/tarfile.py in Python through 3.8.3, an attacker is able to craft a TAR archive leading to an infinite loop when opened by tarfile.open, because _proc_pax lacks header validation. En la biblioteca Lib/tarfile.py en Python versiones hasta 3.8.3, un atacante puede diseñar un archivo TAR conllevando a un bucle infinito cuando se abrió mediante tarfile.open, porque la función _proc_pax carece de comprobación de encabezado A flaw was found in python.

In Python 3.6 through 3.6.10, 3.7 through 3.7.8, 3.8 through 3.8.4rc1, and 3.9 through 3.9.0b4 on Windows, a Trojan horse python3.dll might be used in cases where CPython is embedded in a native application. This occurs because python3X.dll may use an invalid search path for python3.dll loading (after Py_SetPath has been used). NOTE: this issue CANNOT occur when using python.exe from a standard (non-embedded) Python installation on Windows. En Python versiones 3.6 hasta 3.6.10, 3.7 hasta 3.7.8, 3.8 hasta 3.8.4rc1 y 3.9 hasta 3.9.0b4 en Windows, se puede usar una python3.dll de tipo caballo de Troya en los casos en que CPython está incorporado en una aplicación nativa. Esto se produce porque python3X.dll puede usar una ruta de búsqueda no válida para cargar python3.dll (después de que haya sido usado Py_SetPath). • https://bugs.python.org/issue29778 https://github.com/python/cpython/pull/21297 https://security.netapp.com/advisory/ntap-20210312-0004 • CWE-427: Uncontrolled Search Path Element CWE-908: Use of Uninitialized Resource •
CVSS: 5.9EPSS: 1%CPEs: 9EXPL: 0CVE-2020-14422 – python: DoS via inefficiency in IPv{4,6}Interface classes
https://notcve.org/view.php?id=CVE-2020-14422
Lib/ipaddress.py in Python through 3.8.3 improperly computes hash values in the IPv4Interface and IPv6Interface classes, which might allow a remote attacker to cause a denial of service if an application is affected by the performance of a dictionary containing IPv4Interface or IPv6Interface objects, and this attacker can cause many dictionary entries to be created. This is fixed in: v3.5.10, v3.5.10rc1; v3.6.12; v3.7.9; v3.8.4, v3.8.4rc1, v3.8.5, v3.8.6, v3.8.6rc1; v3.9.0, v3.9.0b4, v3.9.0b5, v3.9.0rc1, v3.9.0rc2. La biblioteca Lib/ipaddress.py en Python versiones hasta 3.8.3, calcula inapropiadamente los valores de hash en las clases IPv4Interface e IPv6Interface, lo que podría permitir a un atacante remoto causar una denegación de servicio si una aplicación está afectada por el desempeño de un diccionario que contiene objetos de IPv4Interface o IPv6Interface, y este atacante puede causar que muchas entradas de diccionario sean creadas. Esto esta corregido en las versiones: v3.5.10, v3.5.10rc1; v3.6.12; v3.7.9; v3.8.4, v3.8.4rc1, v3.8.5, v3.8.6, v3.8.6rc1; v3.9.0, v3.9.0b4, v3.9.0b5, v3.9.0rc1, v3.9.0rc2 A vulnerability was found in the way the ipaddress python module computes hash values in the IPv4Interface and IPv6Interface classes. This flaw allows an attacker to create many dictionary entries, due to the performance of a dictionary containing the IPv4Interface or IPv6Interface objects, possibly resulting in a denial of service. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00041.html https://bugs.python.org/issue41004 https://github.com/python/cpython/pull/20956 https://lists.debian.org/debian-lts-announce/2020/07/msg00011.html https://lists.debian.org/debian-lts-announce/2023/ • CWE-330: Use of Insufficiently Random Values CWE-400: Uncontrolled Resource Consumption CWE-682: Incorrect Calculation •
