Description

A flaw was found in libsoup. A remote attacker could exploit an unsigned to signed conversion error in the `soup_body_input_stream_read_chunked()` function by sending a malicious HTTP request.

Successful exploitation can allow an attacker to bypass security controls, poison web caches, or gain unauthorized access.
