TencentOS Server 3: libsoup (TSSA-2025:0357)

high Nessus Plugin ID 239101

Synopsis

The remote TencentOS Server 3 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0357 advisory.

Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

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

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

CVE-2025-32053:
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-2025-32906:
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-2025-32911:
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-2025-32913:
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-2025-46420:
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-2025-46421:
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.

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.
