There is no fixed version for libsoup.
Overview
Affected versions of this package are vulnerable to Out-of-bounds Read in the soup_multipart_input_stream_read_headers function when processing multipart payloads with an oversized boundary string. An attacker can cause the application to crash or potentially access unauthorized memory fragments by sending specially crafted HTTP responses containing malformed or excessively large boundary parameters.
Workaround
This vulnerability can be mitigated by restricting network access to applications that process multipart messages from untrusted sources, implementing firewall rules to limit incoming connections to trusted clients, and ensuring that services using the affected component are not exposed to untrusted networks.
