https://notcve.org/view.php?id=CVE-2022-42919
Python 3.9.x before 3.9.16 and 3.10.x before 3.10.9 on Linux allows local privilege escalation in a non-default configuration. The Python multiprocessing library, when used with the forkserver start method on Linux, allows pickles to be deserialized from any user in the same machine local network namespace, which in many system configurations means any user on the same machine. Pickles can execute arbitrary code. Thus, this allows for local user privilege escalation to the user that any forkserver process is running as. Setting multiprocessing.util.abstract_sockets_supported to False is a workaround. • https://github.com/python/cpython/compare/v3.10.8...v3.10.9 https://github.com/python/cpython/compare/v3.9.15...v3.9.16 https://github.com/python/cpython/issues/97514 https://github.com/python/cpython/issues/97514#issuecomment-1310277840 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FKGCQPIVHEAIJ77R3RSNSQWYBUDVWDKU https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/P2LHWWEI5OBQ6RELULMVU6KMDYG4WZXH https://lists.fedo • CWE-269: Improper Privilege Management •

https://notcve.org/view.php?id=CVE-2022-37454
The Keccak XKCP SHA-3 reference implementation before fdc6fef has an integer overflow and resultant buffer overflow that allows attackers to execute arbitrary code or eliminate expected cryptographic properties. This occurs in the sponge function interface. La implementación de referencia de Keccak XKCP SHA-3 versiones anteriores a fdc6fef, presenta un desbordamiento de enteros y un desbordamiento de búfer resultante que permite a atacantes ejecutar código arbitrario o eliminar las propiedades criptográficas esperadas. Esto ocurre en la interfaz de la función sponge A flaw was found in the Keccak XKCP SHA-3 reference implementation.

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.

https://notcve.org/view.php?id=CVE-2015-20107
In Python (aka CPython) up to 3.10.8, the mailcap module does not add escape characters into commands discovered in the system mailcap file. This may allow attackers to inject shell commands into applications that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or arguments). The fix is also back-ported to 3.7, 3.8, 3.9 En Python (también conocido como CPython) hasta la versión 3.10.8, el módulo mailcap no añade caracteres de escape en los comandos descubiertos en el archivo mailcap del sistema. Esto puede permitir a los atacantes inyectar comandos de shell en aplicaciones que llamen a mailcap.findmatch con entradas no confiables (si carecen de validación de los nombres de archivos o argumentos proporcionados por el usuario). La corrección también se ha aplicado a las versiones 3.7, 3.8 y 3.9 A command injection vulnerability was found in the Python mailcap module. • https://bugs.python.org/issue24778 https://github.com/python/cpython/issues/68966 https://lists.debian.org/debian-lts-announce/2023/05/msg00024.html https://lists.debian.org/debian-lts-announce/2023/06/msg00039.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/46KWPTI72SSEOF53DOYQBQOCN4QQB2GE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/53TQZFLS6O3FLIMVSXFEEPZSWLDZLBOX https://lists.fedoraproject.org/archives/list/package-announ • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
