    CVE ID         : CVE-2022-40897 CVE-2024-6345
    Debian Bug     :

    Brief introduction

    CVE-2022-40897

        setuptools before 65.5.1 allows remote attackers to cause a denial
        of service via HTML in a crafted package or custom PackageIndex
        page. There is a Regular Expression Denial of Service (ReDoS)
        inpackage_index.py.

    CVE-2024-6345

        A vulnerability in the package_index module allows for remote code
        execution via its download functions. These functions, which are
        used to download packages from URLs provided by users or retrieved
        from package index servers, are susceptible to code injection. If
        these functions are exposed to user-controlled inputs, such as
        package URLs, they can execute arbitrary commands on the system.

    For Debian 11 bullseye, these problems have been fixed in version
    52.0.0-4+deb11u1.

    We recommend that you upgrade your setuptools packages.
