It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-961 advisory.

    A flaw was found in libsoup. The implementation of HTTP range requests is vulnerable to a resource     consumption attack. This flaw allows a malicious client to request the same range many times in a single     HTTP request, causing the server to use large amounts of memory. (CVE-2025-32907)

    A flaw was found in libsoup. The HTTP/2 server in libsoup may not fully validate the values of pseudo-     headers :scheme, :authority, and :path, which may allow a user to cause a denial of service (DoS).
    (CVE-2025-32908)

    A flaw was found in libsoup, where 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. (CVE-2025-32914)

An update of the libsoup package has been released.

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0587 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2025-32907:
    A use-after-free type vulnerability was found in libsoup, 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-2025-32052:
    A flaw was found in libsoup. The implementation of HTTP range requests is vulnerable to a resource     consumption attack. This flaw allows a malicious client to request the same range many times in a single     HTTP request, causing the server to use large amounts of memory. This does not allow for a full denial of     service.

    CVE-2025-2784:
    A flaw was found in libsoup, where 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.

    CVE-2025-32053:
    A flaw was found in libsoup, where 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-2025-32906:
    A flaw was found in libsoup. The HTTP/2 server in libsoup may not fully validate the values of pseudo-     headers :scheme, :authority, and :path, which may allow a user to cause a denial of service (DoS).

    CVE-2025-32913:
    A flaw was found in libsoup, where 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-2025-32050:
    A flaw was found in libsoup. 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-2025-32912:
    A flaw was found in libsoup. The libsoup append_param_quoted() function may contain an overflow bug     resulting in a buffer under-read.

    CVE-2025-32911:
    A flaw was found in libsoup. A vulnerability in the sniff_unknown() function may lead to heap buffer over-     read.

    CVE-2025-32914:
    A flaw was found in libsoup. A vulnerability in sniff_feed_or_html() and skip_insignificant_space()     functions may lead to a heap buffer over-read.

    CVE-2025-32908:
    A flaw was found in libsoup, where SoupAuthDigest is vulnerable to a NULL pointer dereference. The HTTP     server may cause the libsoup client to crash.

The remote Redhat Enterprise Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2025:7505 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: Heap buffer over-read in `skip_insignificant_space` when sniffing content (CVE-2025-2784)

    * libsoup: Out of bounds reads in soup_headers_parse_request() (CVE-2025-32906)

    * libsoup: Denial of service on libsoup through HTTP/2 server (CVE-2025-32908)

    * libsoup: NULL pointer dereference in client when server  omits the nonce parameter in an Unauthorized     response with Digest  authentication (CVE-2025-32912)

    * 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: Information disclosure may leads libsoup client sends Authorization header to a different host     when being redirected by a server (CVE-2025-46421)
