Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA and Red Hat. Impact type from CWE-787 and the CVSS impact.

Summary

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).
