A flaw was found in libsoup. The SoupWebsocketConnection may accept a large WebSocket message, which may cause libsoup to allocate memory and lead to a denial of service (DoS).

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2025:8663 advisory.

    The libsoup packages provide an HTTP client and server library for GNOME.

    Security Fix(es):

    * libsoup: Heap buffer over-read in `skip_insignificant_space` when sniffing content (CVE-2025-2784)

    * libsoup: Denial of Service attack to websocket server (CVE-2025-32049)

    * libsoup: OOB Read on libsoup through function  soup_multipart_new_from_message in soup-multipart.c     leads to crash or  exit of process (CVE-2025-32914)

    * libsoup: Integer Underflow in soup_multipart_new_from_message() Leading to Denial of Service in libsoup     (CVE-2025-4948)

The remote Redhat Enterprise Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2025:8128 advisory.

    Libsoup is an HTTP library implementation in C. It was originally part of a SOAP (Simple Object Access     Protocol) implementation called Soup, but the SOAP and non-SOAP parts have now been split into separate     packages.  libsoup uses the Glib main loop and is designed to work well with GTK applications. This     enables GNOME applications to access HTTP servers on the network in a completely asynchronous fashion,     very similar to the Gtk+ programming model (a synchronous operation mode is also supported for those who     want it), but the SOAP parts were removed long ago.

    Security Fix(es):

    * libsoup: Denial of Service attack to websocket server (CVE-2025-32049)

    * libsoup: Denial of service in server when client requests a large amount of  overlapping ranges with     Range header (CVE-2025-32907)

    * libsoup: Cookie domain validation bypass via uppercase characters in libsoup (CVE-2025-4035)

    Several security vulnerabilities have been discovered in libsoup2.4, a http     client/server library popularly used in GNOME, et.al.

    CVE-2025-2784

        The package is vulnerable to a heap buffer over-read when sniffing content         via the skip_insight_whitespace() function. Libsoup clients may read one         byte out-of-bounds in response to a crafted HTTP response by an HTTP         server.

    CVE-2025-32050

        The libsoup append_param_quoted() function may contain an overflow bug         resulting in a buffer under-read.

    CVE-2025-32052

        A vulnerability in the sniff_unknown() function may lead to heap buffer         over-read.

    CVE-2025-32053

        A vulnerability in sniff_feed_or_html() and skip_insignificant_space()         functions may lead to a heap buffer over-read.

    CVE-2025-32906

        The soup_headers_parse_request() function may be vulnerable to an         out-of-bound read. This flaw allows a malicious user to use a specially         crafted HTTP request to crash the HTTP server.

    CVE-2025-32909

        SoupContentSniffer may be vulnerable to a NULL pointer dereference in the         sniff_mp4 function. The HTTP server may cause the libsoup client to crash.

    CVE-2025-32910

        A flaw was found in libsoup, where soup_auth_digest_authenticate() is         vulnerable to a NULL pointer dereference. This issue may cause the libsoup         client to crash.

    CVE-2025-32911

        Vulnerable to a use-after-free memory issue not on the heap in the         soup_message_headers_get_content_disposition() function.
        This flaw allows a malicious HTTP client to cause memory corruption in the         libsoup server.

    CVE-2025-32912

        SoupAuthDigest is vulnerable to a NULL pointer dereference. The HTTP server         may cause the libsoup client to crash.

    CVE-2025-32913

        The soup_message_headers_get_content_disposition() function is vulnerable         to a NULL pointer dereference. This flaw allows a malicious HTTP peer to         crash a libsoup client or server that uses this function.

    CVE-2025-32914

        The soup_multipart_new_from_message() function is vulnerable to an         out-of-bounds read. This flaw allows a malicious HTTP client to induce the         libsoup server to read out of bounds.

    Additionally this update also includes a fix to extend the lifetime     of a certificate used by the test-suite during build to avoid     expiring soon.

    Note that this update does *not* yet address CVE-2025-32907 and CVE-2025-32049     which are still being discussed.

    For Debian 11 bullseye, these problems have been fixed in version     2.72.0-2+deb11u2.

    We recommend that you upgrade your libsoup2.4 packages.

    For the detailed security status of libsoup2.4 please refer to     its security tracker page at:
