    libsoup is an HTTP client/server library for GNOME. It uses GObjects and the
    glib main loop, to integrate well with GNOME applications.

    CVE-2025-4476

        A denial-of-service vulnerability has been identified in the libsoup
        HTTP client library. This flaw can be triggered when a libsoup client
        receives a 401 (Unauthorized) HTTP response containing a specifically
        crafted domain parameter within the WWW-Authenticate header. Processing
        this malformed header can lead to a crash of the client application
        using libsoup. An attacker could exploit this by setting up a malicious
        HTTP server. If a user's application using the vulnerable libsoup
        library connects to this malicious server, it could result in a
        denial-of-service. Successful exploitation requires tricking a user's
        client application into connecting to the attacker's malicious server.

    CVE-2025-4945

        A flaw was found in the cookie parsing logic of the libsoup HTTP
        library, used in GNOME applications and other software. The
        vulnerability arises when processing the expiration date of cookies,
        where a specially crafted value can trigger an integer overflow. This
        may result in undefined behavior, allowing an attacker to bypass cookie
        expiration logic, causing persistent or unintended cookie behavior. The
        issue stems from improper validation of large integer inputs during date
        arithmetic operations within the cookie parsing routines.

    CVE-2025-4948

        A flaw was found in the soup_multipart_new_from_message() function of
        the libsoup HTTP library, which is commonly used by GNOME and other
        applications to handle web communications. The issue occurs when the
        library processes specially crafted multipart messages. Due to improper
        validation, an internal calculation can go wrong, leading to an integer
        underflow. This can cause the program to access invalid memory and
        crash. As a result, any application or server using libsoup could be
        forced to exit unexpectedly, creating a denial-of-service (DoS) risk.

    CVE-2025-4969

        A vulnerability was found in the libsoup package. This flaw stems from
        its failure to correctly verify the termination of multipart HTTP
        messages. This can allow a remote attacker to send a specially crafted
        multipart HTTP body, causing the libsoup-consuming server to read beyond
        its allocated memory boundaries (out-of-bounds read).

    For Debian 11 bullseye, these problems have been fixed in version
    2.72.0-2+deb11u3.

    We recommend that you upgrade your libsoup2.4 packages.
