CVE-2025-4435

A flaw was found in CPython's tarfile module. This vulnerability allows unauthorized file extraction via crafted tar archives when TarFile.errorlevel=0, bypassing expected filtering mechanisms.

The severity of this vulnerability was lowered due to the fact that successful exploitation requires the attacker to convince a privileged user or process to extract a malicious tar file. Since tar file extraction typically occurs in trusted contexts or with elevated privileges, the impact is reduced by the requirement of such access.

Versions of python36:3.6/python36 as shipped with Red Hat Enterprise Linux 8 are marked as 'Not affected' as they just provide "symlinks" to the main python3 component, which provides the actual interpreter of the Python programming language.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
