NVD Description

Note: Versions mentioned in the description apply only to the upstream libsoup package and not the libsoup package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

A flaw was found in libsoup. An attacker controlling the value used to set the Content-Type header can inject a Carriage Return Line Feed (CRLF) sequence due to improper input sanitization in the soup_message_headers_set_content_type() function. This vulnerability allows for the injection of arbitrary header-value pairs, potentially leading to HTTP header injection and response splitting attacks.
