https://notcve.org/view.php?id=CVE-2023-6597
An issue was found in the CPython `tempfile.TemporaryDirectory` class affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, and 3.8.18 and prior. The tempfile.TemporaryDirectory class would dereference symlinks during cleanup of permissions-related errors. This means users which can run privileged programs are potentially able to modify permissions of files referenced by symlinks in some circumstances. Se encontró un problema en la clase CPython `tempfile.TemporaryDirectory` que afecta a las versiones 3.12.2, 3.11.8, 3.10.13, 3.9.18 y 3.8.18 y anteriores. La clase tempfile.TemporaryDirectory eliminaría la referencia a enlaces simbólicos durante la limpieza de errores relacionados con permisos. Esto significa que los usuarios que pueden ejecutar programas privilegiados pueden modificar los permisos de los archivos a los que hacen referencia los enlaces simbólicos en algunas circunstancias. • http://www.openwall.com/lists/oss-security/2024/03/20/5 https://github.com/python/cpython/commit/02a9259c717738dfe6b463c44d7e17f2b6d2cb3a https://github.com/python/cpython/commit/5585334d772b253a01a6730e8202ffb1607c3d25 https://github.com/python/cpython/commit/6ceb8aeda504b079fef7a57b8d81472f15cdd9a5 https://github.com/python/cpython/commit/81c16cd94ec38d61aa478b9a452436dc3b1b524d https://github.com/python/cpython/commit/8eaeefe49d179ca4908d052745e3bb8b6f238f82 https://github.com/python/cpython/commit/d54e22a669ae6e987199bb5d2c69bb5a46b0083b https://github.com • CWE-61: UNIX Symbolic Link (Symlink) Following •
CVSS: 6.2EPSS: 0%CPEs: 5EXPL: 0CVE-2024-0450 – Quoted zip-bomb protection for zipfile
https://notcve.org/view.php?id=CVE-2024-0450
An issue was found in the CPython `zipfile` module affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, and 3.8.18 and prior. The zipfile module is vulnerable to “quoted-overlap” zip-bombs which exploit the zip format to create a zip-bomb with a high compression ratio. The fixed versions of CPython makes the zipfile module reject zip archives which overlap entries in the archive. Se encontró un problema en el módulo `zipfile` de CPython que afecta a las versiones 3.12.2, 3.11.8, 3.10.13, 3.9.18 y 3.8.18 y anteriores. El módulo zipfile es vulnerable a bombas zip "superpuestas entre comillas" que explotan el formato zip para crear una bomba zip con una alta relación de compresión. Las versiones fijas de CPython hacen que el módulo zipfile rechace archivos zip que se superponen con entradas en el archivo. • http://www.openwall.com/lists/oss-security/2024/03/20/5 https://github.com/python/cpython/commit/30fe5d853b56138dbec62432d370a1f99409fc85 https://github.com/python/cpython/commit/66363b9a7b9fe7c99eba3a185b74c5fdbf842eba https://github.com/python/cpython/commit/70497218351ba44bffc8b571201ecb5652d84675 https://github.com/python/cpython/commit/a2c59992e9e8d35baba9695eb186ad6c6ff85c51 https://github.com/python/cpython/commit/a956e510f6336d5ae111ba429a61c3ade30a7549 https://github.com/python/cpython/commit/d05bac0b74153beb541b88b4fca33bf053990183 https://github.com • CWE-405: Asymmetric Resource Consumption (Amplification) CWE-450: Multiple Interpretations of UI Input •

https://notcve.org/view.php?id=CVE-2023-50447
Pillow through 10.1.0 allows PIL.ImageMath.eval Arbitrary Code Execution via the environment parameter, a different vulnerability than CVE-2022-22817 (which was about the expression parameter). Pillow hasta la versión 10.1.0 permite la ejecución de código arbitrario PIL.ImageMath.eval a través del parámetro de entorno, una vulnerabilidad diferente a CVE-2022-22817 (que se refería al parámetro de expresión). A vulnerability was found in Pillow, a popular Python imaging library. The flaw identified in the PIL.ImageMath.eval function enables arbitrary code execution by manipulating the environment parameter. • http://www.openwall.com/lists/oss-security/2024/01/20/1 https://devhub.checkmarx.com/cve-details/CVE-2023-50447 https://duartecsantos.github.io/2024-01-02-CVE-2023-50447 https://github.com/python-pillow/Pillow/releases https://lists.debian.org/debian-lts-announce/2024/01/msg00019.html https://access.redhat.com/security/cve/CVE-2023-50447 https://bugzilla.redhat.com/show_bug.cgi?id=2259479 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-95: Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection') •
CVSS: 6.1EPSS: 0%CPEs: 3EXPL: 0CVE-2023-6507 – Groups not dropped before running subprocess when using empty 'extra_groups' parameter
https://notcve.org/view.php?id=CVE-2023-6507
An issue was found in CPython 3.12.0 `subprocess` module on POSIX platforms. The issue was fixed in CPython 3.12.1 and does not affect other stable releases. When using the `extra_groups=` parameter with an empty list as a value (ie `extra_groups=[]`) the logic regressed to not call `setgroups(0, NULL)` before calling `exec()`, thus not dropping the original processes' groups before starting the new process. There is no issue when the parameter isn't used or when any value is used besides an empty list. This issue only impacts CPython processes run with sufficient privilege to make the `setgroups` system call (typically `root`). Se encontró un problema en el módulo `subproceso` de CPython 3.12.0 en plataformas POSIX. El problema se solucionó en CPython 3.12.1 y no afecta a otras versiones estables. • https://github.com/python/cpython/commit/10e9bb13b8dcaa414645b9bd10718d8f7179e82b https://github.com/python/cpython/commit/85bbfa8a4bbdbb61a3a84fbd7cb29a4096ab8a06 https://github.com/python/cpython/commit/9fe7655c6ce0b8e9adc229daf681b6d30e6b1610 https://github.com/python/cpython/issues/112334 https://mail.python.org/archives/list/security-announce@python.org/thread/AUL7QFHBLILGISS7U63B47AYSSGJJQZD • CWE-269: Improper Privilege Management •
