CVE-2023-6507
Description
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.
Statement
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.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
