CVE-2024-52531

GNOME 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).

A flaw was found in the libsoup library. Decoding specially crafted UTF-8 input data with the soup_header_parse_param_list_strict function can cause a heap-based buffer overflow, potentially resulting in code execution and denial of service to applications linked to the library.

It was discovered that libsoup ignored certain characters at the end of header names. A remote attacker could possibly use this issue to perform a HTTP request smuggling attack. It was discovered that libsoup did not correctly handle memory while performing UTF-8 conversions. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. It was discovered that libsoup could enter an infinite loop when reading certain websocket data. An attacker could possibly use this issue to cause a denial of service.
