    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.
