Description
A request smuggling vulnerability exists in libsoup's HTTP/1 header parsing logic. The soup_message_headers_append_common() function in libsoup/soup-message-headers.c unconditionally appends each header value without validating for duplicate or conflicting Content-Length fields. This allows an attacker to send HTTP requests containing multiple Content-Length headers with differing values.
Affected configurations
• gnome libsoup
• redhat enterprise linux 6.0
• redhat enterprise linux 7.0
• redhat enterprise linux 8.0
• redhat enterprise linux 9.0
• redhat enterprise linux 10.0
