    Package        : python-werkzeug     Version        : 0.14.1+dfsg1-4+deb10u2     CVE ID         : CVE-2023-23934 CVE-2023-25577     Debian Bug     : 1031370

    Two vulnerabilities were discovered in Werkzeug, a collection of     utilities for WSGI (web) applications. An attacker may inject cookies     in specific situations, and cause a denial of service (DoS).

    CVE-2023-23934

        Werkzeug will parse the cookie `=__Host-test=bad` as
        __Host-test=bad`. If a Werkzeug application is running next to a         vulnerable or malicious subdomain which sets such a cookie using a         vulnerable browser, the Werkzeug application will see the bad         cookie value but the valid cookie key. Browsers may allow         nameless cookies that look like `=value` instead of         `key=value`. A vulnerable browser may allow a compromised         application on an adjacent subdomain to exploit this to set a         cookie like `=__Host-test=bad` for another subdomain.

    CVE-2023-25577

        Werkzeug's multipart form data parser will parse an unlimited         number of parts, including file parts. Parts can be a small amount         of bytes, but each requires CPU time to parse and may use more         memory as Python data. If a request can be made to an endpoint         that accesses `request.data`, `request.form`, `request.files`, or         `request.get_data(parse_form_data=False)`, it can cause         unexpectedly high resource usage. This allows an attacker to cause         a denial of service by sending crafted multipart data to an         endpoint that will parse it.

    For Debian 10 buster, these problems have been fixed in version     0.14.1+dfsg1-4+deb10u2.

    We recommend that you upgrade your python-werkzeug packages.
