CVE-2019-20907 – python: infinite loop in the tarfile module via crafted TAR archive
https://notcve.org/view.php?id=CVE-2019-20907
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.

CVE-2020-15523
https://notcve.org/view.php?id=CVE-2020-15523
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 •

CVE-2020-11538 – python-pillow: out-of-bounds reads/writes in the parsing of SGI image files in expandrow/expandrow2
https://notcve.org/view.php?id=CVE-2020-11538
In libImaging/SgiRleDecode.c in Pillow through 7.0.0, a number of out-of-bounds reads exist in the parsing of SGI image files, a different issue than CVE-2020-5311. En la biblioteca libImaging/SgiRleDecode.c en Pillow versiones hasta 7.0.0, se presentan múltiples lecturas fuera de límites en el análisis de archivos de imagen SGI, un problema diferente de CVE-2020-5311 An out-of-bounds read/write flaw was found in python-pillow, in the way SGI RLE images are decoded. An application that uses python-pillow to decode untrusted images may be vulnerable. This flaw allows an attacker to crash the application or potentially execute code on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • https://github.com/python-pillow/Pillow/pull/4504 https://github.com/python-pillow/Pillow/pull/4538 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BEBCPE4F2VHTIT6EZA2YZQZLPVDEBJGD https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HOKHNWV2VS5GESY7IBD237E7C6T3I427 https://pillow.readthedocs.io/en/stable/releasenotes/7.1.0.html https://pillow.readthedocs.io/en/stable/releasenotes/index.html https://usn.ubuntu.com/4430-1 https: • CWE-122: Heap-based Buffer Overflow CWE-125: Out-of-bounds Read •
