    Package        : python-pip
    Version        : 20.3.4-4+deb11u2
    CVE ID         : CVE-2023-5752 CVE-2025-8869
    Debian Bug     : 1116336

    Multiple vulnerabilities have been found in python-pip, the Python
    package installer.

    CVE-2023-5752

       When installing a package from a Mercurial VCS URL, arbitrary
       configuration options could be injected to the hg clone call.

    CVE-2025-8869

       Pip's tar extraction doesn't check that symbolic links point to the
       extraction directory.

    For Debian 11 bullseye, these problems have been fixed in version
    20.3.4-4+deb11u2.

    We recommend that you upgrade your python-pip packages.

    For the detailed security status of python-pip please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/python-pip
