"According to the versions of the python-pip packages installed, the EulerOS Virtualization installation on the remote
host is affected by the following vulnerabilities :

    When extracting a tar archive pip may not check symbolic links point into the extraction directory if the
    tarfile module doesn't implement PEP 706.Note that upgrading pip to a 'fixed' version for this
    vulnerability doesn't fix all known vulnerabilities that are remediated by using a Python version that
    implements PEP 706.Note that this is a vulnerability in pip's fallback implementation of tar extraction
    for Python versions that don't implement PEP 706 and therefore are not secure to all vulnerabilities in
    the Python 'tarfile' module. If you're using a Python version that implements PEP 706 then pip doesn't use
    the 'vulnerable' fallback code.Mitigations include upgrading to a version of pip that includes the fix,
    upgrading to a Python version that implements PEP 706 (Python =3.9.17, =3.10.12, =3.11.4, or
    =3.12),applying the linked patch, or inspecting source distributions (sdists) before installation as is
    already a best-practice.(CVE-2025-8869)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization python-pip security
advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
