https://notcve.org/view.php?id=CVE-2020-15523
04 Jul 2020 — 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.... • https://bugs.python.org/issue29778 • CWE-427: Uncontrolled Search Path Element CWE-908: Use of Uninitialized Resource •

CVE-2020-14422 – python: DoS via inefficiency in IPv{4,6}Interface classes
https://notcve.org/view.php?id=CVE-2020-14422
18 Jun 2020 — 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... • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00003.html • CWE-330: Use of Insufficiently Random Values CWE-400: Uncontrolled Resource Consumption CWE-682: Incorrect Calculation •

CVE-2020-13757 – python-rsa: decryption of ciphertext leads to DoS
https://notcve.org/view.php?id=CVE-2020-13757
01 Jun 2020 — Python-RSA before 4.1 ignores leading '\0' bytes during decryption of ciphertext. This could conceivably have a security-relevant impact, e.g., by helping an attacker to infer that an application uses Python-RSA, or if the length of accepted ciphertext affects application behavior (such as by causing excessive memory allocation). Python-RSA versión 4.1, ignora bytes '\0' principales durante la desencriptación del texto cifrado. Esto podría tener un impacto relevante para la seguridad, por ejemplo, al ayudar... • https://github.com/sybrenstuvel/python-rsa/issues/146 • CWE-327: Use of a Broken or Risky Cryptographic Algorithm •

20 Apr 2020 — python-markdown2 through 2.3.8 allows XSS because element names are mishandled unless a \w+ match succeeds. For example, an attack might use elementname@ or elementname- with an onclick attribute. python-markdown2 versiones hasta 2.3.8, permite un ataque de tipo XSS porque los nombres de los elementos se manejan inapropiadamente a menos que una coincidencia de \w+ tenga éxito. Por ejemplo, un ataque podría usar elementname@ o elementname- con un atributo onclick. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00031.html • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
