CVSS: 7.5EPSS: 0%CPEs: 23EXPL: 0CVE-2020-10735 – python: int() type in PyLong_FromString() does not limit amount of digits converting text to int leading to DoS
https://notcve.org/view.php?id=CVE-2020-10735
A flaw was found in python. In algorithms with quadratic time complexity using non-binary bases, when using int("text"), a system could take 50ms to parse an int string with 100,000 digits and 5s for 1,000,000 digits (float, decimal, int.from_bytes(), and int() for binary bases 2, 4, 8, 16, and 32 are not affected). The highest threat from this vulnerability is to system availability. Se ha encontrado un fallo en python. En los algoritmos con complejidad de tiempo cuadrática que usan bases no binarias, cuando es usada int("text"), un sistema podría tardar 50ms en analizar una cadena int con 100.000 dígitos y 5s para 1.000.000 de dígitos (float, decimal, int.from_bytes(), e int() para bases binarias 2, 4, 8, 16, y 32 no están afectados). • http://www.openwall.com/lists/oss-security/2022/09/21/1 http://www.openwall.com/lists/oss-security/2022/09/21/4 https://access.redhat.com/security/cve/CVE-2020-10735 https://bugzilla.redhat.com/show_bug.cgi?id=1834423 https://docs.google.com/document/d/1KjuF_aXlzPUxTK4BMgezGJ2Pn7uevfX7g0_mvgHlL7Y https://github.com/python/cpython/issues/95778 https://lists.debian.org/debian-lts-announce/2023/06/msg00039.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fed • CWE-400: Uncontrolled Resource Consumption CWE-704: Incorrect Type Conversion or Cast •
CVSS: 7.4EPSS: 0%CPEs: 17EXPL: 0CVE-2021-28861 – python: open redirection vulnerability in lib/http/server.py may lead to information disclosure
https://notcve.org/view.php?id=CVE-2021-28861
Python 3.x through 3.10 has an open redirection vulnerability in lib/http/server.py due to no protection against multiple (/) at the beginning of URI path which may leads to information disclosure. NOTE: this is disputed by a third party because the http.server.html documentation page states "Warning: http.server is not recommended for production. It only implements basic security checks." ** EN DISPUTA ** Python versiones 3.x hasta la versión 3.10, presenta una vulnerabilidad de redireccionamiento abierto en el archivo lib/http/server.py debido a una falta de protección contra múltiples (/) al principio de la ruta URI que puede conllevar a una divulgación de información. NOTA: esto es discutido por un tercero porque la página de documentación http.server.html dice "Advertencia: http.server no se recomienda para producción. Sólo implementa controles de seguridad básicos". • https://bugs.python.org/issue43223 https://github.com/python/cpython/pull/24848 https://github.com/python/cpython/pull/93879 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2TRINJE3INWDVIHIABW4L2NP3RUSK7BJ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5LTSPFIULY2GZJN3QYNFVM4JSU6H4D6J https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5OABQ5CMPQETJLFHROAXDIDXCMDTNVYG https://lists.fedoraproject.org/archives&# • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
CVSS: 7.0EPSS: 0%CPEs: 13EXPL: 0CVE-2022-26488
https://notcve.org/view.php?id=CVE-2022-26488
In Python before 3.10.3 on Windows, local users can gain privileges because the search path is inadequately secured. The installer may allow a local attacker to add user-writable directories to the system search path. To exploit, an administrator must have installed Python for all users and enabled PATH entries. A non-administrative user can trigger a repair that incorrectly adds user-writable paths into PATH, enabling search-path hijacking of other users and system services. This affects Python (CPython) through 3.7.12, 3.8.x through 3.8.12, 3.9.x through 3.9.10, and 3.10.x through 3.10.2. • https://mail.python.org/archives/list/security-announce%40python.org/thread/657Z4XULWZNIY5FRP3OWXHYKUSIH6DMN https://security.netapp.com/advisory/ntap-20220419-0005 • CWE-426: Untrusted Search Path •
