The version of libsoup installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-32912 advisory.

  - 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. (CVE-2025-32912)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

According to the versions of the libsoup packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    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-2025-32053)

    A flaw was found in libsoup. A vulnerability in the sniff_unknown() function may lead to heap buffer over-     read.(CVE-2025-32052)

    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-2025-32910)

    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-2025-32911)

    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.(CVE-2025-32912)

    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-2025-32907)

    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-2025-32906)

    A flaw was found in libsoup. 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-2025-32909)

    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-2025-32913)

    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)

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

    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-2025-2784)

    A flaw was found in libsoup. It is vulnerable to memory leaks in the soup_header_parse_quality_list()     function when parsing a quality list that contains elements with all zeroes.(CVE-2025-46420)

    A flaw was found in libsoup. When libsoup clients encounter an HTTP redirect, they mistakenly send the     HTTP Authorization header to the new host that the redirection points to. This allows the new host to     impersonate the user to the original host that issued the redirect.(CVE-2025-46421)

    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-2025-4948)

    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).(CVE-2025-4969)

Tenable has extracted the preceding description block directly from the EulerOS libsoup security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

An update of the libsoup package has been released.

The remote NewStart CGSL host, running version MAIN 7.02, has libsoup packages installed that are affected by multiple vulnerabilities:

  - A flaw was found in libsoup. An integer underflow vulnerability occurs when processing content with a     zero-length resource, leading to a buffer overread. This can allow an attacker to potentially access     sensitive information or cause an application level denial of service. (CVE-2026-2369)

  - GNOME libsoup before 3.6.0 allows HTTP request smuggling in some configurations because '\0' characters at     the end of header names are ignored, i.e., a Transfer-Encoding\0: chunked header is treated the same as     a Transfer-Encoding: chunked header. (CVE-2024-52530)

  - A flaw was found in the cookie date handling logic of the libsoup HTTP library, widely used by GNOME and     other applications for web communication. When processing cookies with specially crafted expiration dates,     the library may perform an out-of-bounds memory read. This flaw could result in unintended disclosure of     memory contents, potentially exposing sensitive information from the process using libsoup.
    (CVE-2025-11021)

  - A flaw in libsoup's HTTP header handling allows multiple Host: headers in a request and returns the last     occurrence for server-side processing. Common front proxies often honor the first Host: header, so this     mismatch can cause vhost confusion where a proxy routes a request to one backend but the backend     interprets it as destined for another host. This discrepancy enables request-smuggling style attacks,     cache poisoning, or bypassing host-based access controls when an attacker supplies duplicate Host headers.
    (CVE-2025-14523)

  - 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-2025-2784)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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.
