EulerOS 2.0 SP11 : libsoup (EulerOS-SA-2025-1960)
medium Nessus Plugin ID 249203
Synopsis
The remote EulerOS host is missing multiple security updates.Description
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 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. 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 denial-of-service vulnerability has been identified in the libsoup HTTP client library. This flaw can be triggered when a libsoup client receives a 401 (Unauthorized) HTTP response containing a specifically crafted domain parameter within the WWW-Authenticate header. Processing this malformed header can lead to a crash of the client application using libsoup. An attacker could exploit this by setting up a malicious HTTP server. If a user's application using the vulnerable libsoup library connects to this malicious server, it could result in a denial-of-service. Successful exploitation requires tricking a user's client application into connecting to the attacker's malicious server.(CVE-2025-4476)
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.
