libsoup: buffer overflow via UTF-8 conversion in soup_header_parse_param_list_strict

Published Nov 11, 2024 CVSS 3.1 · 6.5 Medium EPSS < 1% KEV · Not listed
Description
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).
