NVD Description

Note: Versions mentioned in the description apply only to the upstream libsoup2.4 package and not the libsoup2.4 package as distributed by Ubuntu. See How to fix? for Ubuntu:22.04 relevant fixed versions and status.

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. This vulnerability occurs when libsoup operates behind a non-libsoup proxy server or as a proxy in front of a non-libsoup backend server. Successful exploitation can allow an attacker to bypass security controls, poison web caches, or gain unauthorized access.
