    Package        : python-eventlet
    Version        : 0.26.1-7+deb11u2
    CVE ID         : CVE-2025-58068
    Debian Bug     :

    CVE-2025-58068
        Eventlet is a concurrent networking library for Python. Eventlet WSGI
        parser is vulnerable to HTTP Request Smuggling due to improper
        handling of HTTP trailer sections. This vulnerability could enable
        attackers to, bypass front-end security controls, launch targeted
        attacks against active site users, and poison web caches.

    For Debian 11 bullseye, this problem has been fixed in version
    0.26.1-7+deb11u2.

    We recommend that you upgrade your python-eventlet packages.

    For the detailed security status of python-eventlet please refer to
    its security tracker page at:
