TencentOS Server 4: libsoup3 (TSSA-2025:0587)

medium Nessus Plugin ID 275938

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

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.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

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

Solution

Update the affected packages.
