Overview
Affected versions of this package are vulnerable to Asymmetric Resource Consumption (Amplification) in the soup_message_headers_get_ranges_internal() function. HTTP range requests can be made for overlapping or identical ranges, which are processed nonlinearly. This allows an attacker to occupy large amounts of memory by requesting the same range many times in a single HTTP request.
