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 •
