An update of the libsoup package has been released.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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 relies on the presence of the package as reported by the vendor.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-941 advisory.

    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. 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 libsoup soup_uri_decode_data_uri() function may crash when processing     malformed data URI. This flaw allows an attacker to cause a denial of service (DoS). (CVE-2025-32051)

    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. 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, 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 soup_auth_digest_authenticate() is vulnerable to a NULL pointer     dereference. This issue may cause the libsoup client to crash. (CVE-2025-32910)

    libsoup: Double free on  soup_message_headers_get_content_disposition() through  soup-message-headers.c     via params GHashTable value (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, 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. 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)

Note that Nessus has not tested for these issues 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. 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. 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, 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, 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 SoupAuthDigest is vulnerable to a NULL pointer dereference. The HTTP     server may cause the libsoup client to crash.(CVE-2025-32912)

    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 soup_auth_digest_authenticate() is vulnerable to a NULL pointer     dereference. This issue may cause the libsoup client to crash.(CVE-2025-32910)

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

    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)
