CVE-2025-32911A 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-2025-4948A 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-2025-32913A 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-2025-32908A 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-2025-32906A 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-2025-32049A flaw was found in libsoup. The SoupWebsocketConnection may accept a large WebSocket message, which may cause libsoup to allocate memory and lead to a denial of service (DoS).
CVE-2025-11021A 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-2024-52532GNOME libsoup before 3.6.1 has an infinite loop, and memory consumption. during the reading of certain patterns of WebSocket data from clients.
CVE-2024-52530GNOME 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-2025-32914A 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-2025-32912A 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-2025-32910A 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-2025-32053A 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-2025-32052A flaw was found in libsoup. A vulnerability in the sniff_unknown() function may lead to heap buffer over-read.
CVE-2025-2784A 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-2025-32051A 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-2025-32050A flaw was found in libsoup. The libsoup append_param_quoted() function may contain an overflow bug resulting in a buffer under-read.
CVE-2025-32909A 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-2025-32907A 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-2024-52531GNOME libsoup before 3.6.1 allows a buffer overflow in applications that perform conversion to UTF-8 in soup_header_parse_param_list_strict. There is a plausible way to reach this remotely via soup_message_headers_get_content_type (e.g., an application may want to retrieve the content type of a request or response).
