CVE-2023-6507

A flaw was found in Python's subprocess module. When creating a new subprocess, the developer may specify a list of extra groups through the 'extra_groups=` parameter. When this optional parameter is informed with an empty list, the module fails to properly clean the associated groups from the new sub-process's parent before executing the new sub-process. If the parent process has high privileges, the sub-process created may have unnecessarily high privileges, leading to possible confidentiality and integrity issues when properly exploited.

The Python versions as distributed with Red Hat Enterprise Linux 6, 7, 8 and 9 are not vulnerable to this flaw, as it doesn't contain the affected code or it ships a version where the fix is already present.
