Описание
Allows the extraction filter to be ignored, allowing symlink targets to point outside the destination directory, and the modification of some file metadata.
You are affected by this vulnerability if using the tarfile module to extract untrusted tar archives using TarFile.extractall() or TarFile.extract() using the filter= parameter with a value of "data" or "tar". See the tarfile extraction filters documentation https://docs.python.org/3/library/tarfile.html#tarfile-extraction-filter for more information.
Note that for Python 3.14 or later the default value of filter= changed from "no filtering" to `"data", so if you are relying on this new default behavior then your usage is also affected.
Note that none of these vulnerabilities significantly affect the installation of source distributions which are tar archives as source distributions already allow arbitrary code execution during the build process. However when evaluating source distributions it's important to avoid installing source distributions with suspicious links.
A flaw was found in CPython's tarfile module. This vulnerability allows bypassing of extraction filters, enabling symlink traversal outside the intended extraction directory and potential modification of file metadata via malicious tar archives using TarFile.extractall() or TarFile.extract() with the filter="data" or filter="tar" parameters. This issue leads to potentially overwriting or modifying system files and metadata.
Отчет
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 this 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.
Меры по смягчению последствий
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.
